[SampleProf] Accumulate vtable type counts for FS-discriminator-collapsed locations (#230380)

When reading a profile generated from flow-sensitive binaries,
accumulate vtable profiles for the same masked locations.

This is similar to how LBR samples are merged:

2) Inlined callsite samples are merged at
https://github.com/llvm/llvm-project/blob/47c2af945d58584e450a624098609599237d166e/llvm/lib/ProfileData/SampleProfReader.cpp#L906-L913

[AMDGPU] Limit the fmul fusion discount to a matching context type

The fmul is free when its context instruction feeds a fusable fadd or
fsub. A vector fmul priced with a scalar lane as the context inherits
that fusion only when it is emitted lane by lane. On a packed type the
scalar user does not show that the vector fmul feeds a vector fadd, and
products extracted into a scalar fadd chain keep the packed fmul while
the fma is lost.

iflib: unify prefetching

This change makes all prefetching use the iflib prefetch wrappers, rather
than using prefetch() in some places and __builtin_prefetch() in others.

Note that __builtin_prefetch() does not work in the kernel on amd64 as clang
disables it when -mnosse is specified, so we must use the asm directives there,
and builtin_prefetch() elsewhere.

This change enables prefetching on non-x86 (notably arm64), and it enables
prefetching in netmap that has been there since day one, but which has never worked.

This is a no-op on non-netmap amd64 and i386

[AggressiveInstCombine] Match ctpop table lookups (#231225)

perlbench, gcc and ffmpeg all contain this pattern of ctpop table

```c

    static const char table[256] = {0, 1, 1, 2, 1, 2, 2, 3, 1, 2, 2, 3, 2, 3, 3, 4, 1, 2, 2, 3, 2, 3, 3, 4, 2, 3, 3, 4, 3, 4, 4, 5, 1, 2, 2, 3, 2, 3, 3, 4, 2, 3, 3, 4, 3, 4, 4, 5, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 1, 2, 2, 3, 2, 3, 3, 4, 2, 3, 3, 4, 3, 4, 4, 5, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 3, 4, 4, 5, 4, 5, 5, 6, 4, 5, 5, 6, 5, 6, 6, 7, 1, 2, 2, 3, 2, 3, 3, 4, 2, 3, 3, 4, 3, 4, 4, 5, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 3, 4, 4, 5, 4, 5, 5, 6, 4, 5, 5, 6, 5, 6, 6, 7, 2, 3, 3, 4, 3, 4, 4, 5, 3, 4, 4, 5, 4, 5, 5, 6, 3, 4, 4, 5, 4, 5, 5, 6, 4, 5, 5, 6, 5, 6, 6, 7, 3, 4, 4, 5, 4, 5, 5, 6, 4, 5, 5, 6, 5, 6, 6, 7, 4, 5, 5, 6, 5, 6, 6, 7, 5, 6, 6, 7, 6, 7, 7, 8,};
    return table[x];
}
```

This teaches AggressiveInstCombine to detect them and lower them to a
llvm.ctpop intrinsic if the target reports ctpop is fast.

We need to also teach replaceWithPopCount to handle extending the result
as the loaded result may be wider than the index used as the input.

Note that this will also match on tiny tables e.g. a load of i8 from [2

AMDGPU: Only use 16-bit atomic loads when D16 preserves unused bits

Make the atomic load/store legality match the hardware operand
structure. A 16-bit atomic load only produces a real 16-bit result
with the true16 D16 loads, which require d16PreservesUnusedBits. With
SRAMECC enabled the true16 patterns use a 32-bit load and extract the
low half, so promote i16, f16 and bf16 atomic loads to an i32 extending
load instead. Atomic stores remain 16-bit with real true16, since the
store source is a 16-bit register regardless.

Remove the true16 sramecc atomic load patterns which are now dead.

TableGen: Pack the RecordVal used flag with its type

Every record holds a copy of every field it inherits, so RecordVal makes
up most of tablegen's memory use. Store the used flag alongside the
field kind in the spare low bits of the type pointer instead of in a
separate bool. This shrinks RecordVal from 56 to 48 bytes.

Parsing AMDGPU.td with llvm-tblgen --null-backend, peak memory drops
from 934 MB to 834 MB with 10% fewer page faults.

AMDGPU: Promote 16-bit atomic load/store to extending i32 (#230943)

16-bit atomic loads are really extending loads into a 32-bit register,
and 16-bit atomic stores are truncating stores of a 32-bit value.
Without real true16, promote i16, f16 and bf16 atomic load and store to 
i32 as any-extending loads and truncating stores, matching how regular 
loads and stores are handled. With real true16, select all 16-bit types
directly using the type-generic atomic patterns, as is done for the
wider types.

Teach LegalizeDAG to promote ATOMIC_LOAD and ATOMIC_STORE to a 
wider integer type, preserving the extension type. The i16-only atomic
patterns are now only needed for real true16, so remove the rest.

[llvm] Use a separate macro for LLVM C exports (#230090)

Previously, the LLVM C library reused the `LLVM_EXPORTS` macro to define
the `dllexport` annotation. While this caused no problem with the
resulting build, this caused warnings when building the definitions of
the LLVM C library exports.

This fixes the issue by having a separate macro, `LLVM_C_EXPORTS` for
these exports.

This has no effect outside of the Windows dylib build.

The effort to build LLVM as a dylib is tracked in #109483.

[InstCombine] Fix profiles for SPFs in FoldSelectWithAndOrCond (#231280)

01955119c7740a5e1fdf5bed4ba4434a35fe4613 previously tried to fix the
case in FoldSelectWithAndOrCond where the select is a SPF (select
pattern flavor). However, it incorrectly propagated the profile
information, pulling it from the select passed into the function for
which the conditioon does not match the new select.

This patch fixes that by pulling the branch weights from the logical
select in the comparison if the conditions match and otherwise assigning
unknown branch weights. This should cover a decent portion of cases, and
in other cases we are unable to come up with branch weights.

spa: don't self-heal while loading an older txg

A rewind (zpool import -F/-FX), an import of an explicitly requested txg
(-T) and the dry run of either load a txg older than the newest one on
disk.  Its blocks may have been freed and their space reused by later
txgs, so a copy failing its checksum is expected there.  But the mirror,
raidz and indirect read paths rewrite a failed copy with the contents of
an intact one whenever the pool is writeable, which these loads are, dry
runs included.  The write lands on whatever lives there now: blocks of
later txgs, including the newest one.  A series of
`zpool import -nFX -T` dry runs can leave the pool unimportable
("couldn't get 'config' value in MOS directory").

Only repair when no load is in progress, when the load is of the
newest txg, or once the load has committed to its txg by starting to
sync, so that resilver and rebuild repairs issued from then on, and
self-healing after the import, are unaffected.

This makes import_rewind_dryrun_no_writes pass.

ZTS: add import_rewind_dryrun_no_writes

A dry run of a rewind (zpool import -nFX -T <txg>) loads an older txg
with the pool writeable.  When one copy of an old block has had its
space reused by a later txg and another copy is intact, reading the
intact copy "repairs" the reused one with the old contents, overwriting
live blocks of the newest txg.

The test syncs a small pool many times, dry runs a rewind to every
older txg left in the uberblock ring, and checks that the vdev's
allocatable area is unchanged and that the pool still imports and
scrubs clean.

LV: Expand llvm.histogram intrinsic to support umax, umin, and uadd.sat operations (#127399)

This patch extends the llvm.histogram intrinsic to support additional
update operations beyond the existing add. Specifically, the new
supported operations are:

- umax: unsigned maximum

- umin: unsigned minimum

- uadd.sat: unsigned saturated addition


Changes in this patch include:

- Updates to the Loop Vectorizer (LV) to recognize and handle the new
operations.

- Scalar fallback support added via ScalarizeMaskedMemIntrin for targets
that do not natively support these operations.
