[SimplifyLibCalls] Use constant 64-bit indices for ExtractElement (#209020)
The canonical form preferred by instCombine is to use 64-bit values for
constant index in ExtractElement.
[InstCombine] Use constant 64-bit indices for InsertElement (#209017)
The canonical form preferred by instCombine is to use 64-bit values for
constant index in InsertElement.
[PowerPC] Use constant 64-bit indices for Extract/InsertElement (#209015)
The canonical form preferred by instCombine is to use 64-bit values for
constant index in ExtractElement and InsertElement.
[IR] Use constant 64-bit indices for Extract/InsertElement (#208996)
The canonical form preferred by instCombine is to use 64-bit values for
constant index in ExtractElement and InsertElement
[lld] Report missing --irpgo-profile file instead of asserting (#209028)
When --irpgo-profile names a missing file, takeError() asserts
```
ld.lld: error: No such file or directory
ld.lld: Error.h:686: ... Assertion `!HasError && "Cannot get value when an error exists!"' failed.
```
Check the Expected before use. Fixes #203761

[SLP] Don't truncate compare constants that change value at the demoted width
SLP preserves the original bit width when narrowing compare operands,
but doesn't always account for the required size convertion in LLVM IR.
This can produce incorrect compare constants after truncation.
Fix this by using getSignificantBits() for sign-extended operands,
forbidding truncation for signed predicates on zero-extended operands,
and checking the correct operand in the LBW > RBW case.
[clang-tidy] Fix identifier-naming style lookup in macro arguments (#206809)
Problem statement: the var lambda parameter was written inside a macro
argument. The declaration location was treated as a macro location, and
the filename lookup returned an empty filename for that location.
Fix: use a file location for the style lookup. Alternative options
considered were spelling location and expansion location.
Fixes #154957
