[MC][CodeGen] Add --large-eh-encoding flag for x86_64 & Aarch64 ELF (#174508)
Add a --large-eh-encoding option that forces 8-byte (DW_EH_PE_sdata8)
pointer encodings for all x86_64 & aarch64 ELF EH sections: FDE CFI
encoding, personality, LSDA, and TType encodings.
This is useful for large binaries where .text may exceed 2GB, causing
relocation overflows in .eh_frame and .gcc_except_table even under the
small or medium code model. The cost is purely in section size (a few
extra bytes per FDE/LSDA entry) with no runtime performance impact.
zfs_sync: remove support for impossible scenarios
The superblock pointer will always be set, as will z_log, so remove code
supporting cases that can't occur (on Linux at least).

zfs_sync: return error when pool suspends
If the pool is suspended, we'll just block in zil_commit(). If the
system is shutting down, blocking wouldn't help anyone. So, we should
keep this test for now, but at least return an error for anyone who is
actually interested.

zts: test syncfs() behaviour when pool suspends
Fairly coarse, but if it returns while the pool suspends, it must be

zpl_sync_fs: work around kernels that ignore sync_fs errors
If the kernel will honour our error returns, use them. If not, fool it
by setting a writeback error on the superblock, if available.

[ConstraintElim] Check loop pred & invariance before SCEV query (NFC) (#209314)
Move cheap checks (check for loop predecessor and invariance) before
more expensive SCEV queries.
This slightly reduces the number we need to unnecessarily construct SCEV

[RISCV][P-ext] Fix incorrect shift mask on variable shift instructions. (#209293)
The instructions are defined to read 5 bits regardless of element size.
I think we will also need to change the C intrinsics to allow 5 bit

In preparation for the pass that converts `acc.compute_region` to GPU

related to reductions. Doing so to simplify review and to ensure that
unit testing is added for the utilities.

clang/AMDGPU: Validate -target-cpu in cc1 is valid for the subarch (#206481)
Restrict the reported list of valid target-cpus based on the triple's
subarch. This is more consistent with how other targets validate the
target CPU name. Currently we have split handling validating the target
name for the triple in both the driver and here. The driver based
diagnostic seems to be an amdgpu-ism in 2 different places (though there
is one arm validation emitting the same diagnostic). In the future we could
probably drop those.
