Revert "[VectorCombine] Fold scalar selects from bitcast into vector select" (#174758)

Reverts llvm/llvm-project#173990
Reverting to address post-commit review feedback. Will recommit with
fixes.

[SPIRV] Lower i1 comparisons to logical operations in regularizer pass.

UGT, UGE, ULT, ULE, SGT, SGE, SLT, SLE predicates for i1 types are now
lowered to equivalent logical operations (AND, OR, NOT) to ensure
valid SPIR-V, since SPIR-V boolean types only support logical operations.

Update llvm/lib/Transforms/InstCombine/InstCombineSimplifyDemanded.cpp

[llvm-stress] Allow implicit truncation

This is generating a random integer, so truncating is fine.

Fixes the issue reported in:

worklows/release-binaries: Add Windows release binary builds (#150793)

Windows x86 binaries will now be built and uploaded automatically when a new release is tagged.

[Clang][LLVM][AArch64] Add support for FCVTXNT, FCVTLT, {B}FCVTNT int… (#170356)

…rinsics

This patch adds support in Clang for these assembly instructions
FCVTXNT, FCVTLT, {B}FCVTNT
By implementing these prototypes:

// Variant is available for _f64_f32
svfloat32_t     svcvtlt_f32[_f16]_z     (svbool_t pg, svfloat16_t op);

// Variants are available for:
// _f32_f64, _bf16_f32
svfloat16_t svcvtnt_f16[_f32]_z (svfloat16_t even, svbool_t pg,
svfloat32_t op);

svfloat32_t svcvtxnt_f32[_f64]_z (svfloat32_t even, svbool_t pg,
svfloat64_t op);

Revert "[AA] Improve precision for monotonic atomic load/store operations" (#173135)

Reverts llvm/llvm-project#158169

The improved AA precision for atomic store operations causes the DSE
pass to optimize out the object variables.

[lldb-dap][NFC] Ignore extension built test artefacts. (#174724)

Testing LLDB-DAP vscode extension creates files in the .vscode-test
folder ignore them.

[CodeGen][EarlyIfConversion] Fix typo in loop invariant check lambda

[CodeGen][EarlyIfConvert] Test case documenting current behavior (before typo fix)

In this case the branch is converted even though it's operands are loop invariant - we should let the branch predictor handle this

[Dexter] Replace DAP "initialized" timeout with a warning (#174198)

Fixes https://github.com/llvm/llvm-project/issues/172893.

In the issue reported above there, it appears that LLDB is hitting a 3s
timeout as part of some CI tests; this patch attempts to fix the issue
by replacing the 3s timeout with a 60s timeout, which should be suitably
long for any CI job (lldb-dap itself will automatically time out after
30s, so this should not be hit unless the process hangs).

InstCombine: Introduce nsz flag on minimum/maximum in SimplifyDemandedFPClass

Alive isn't particularly happy with this in the case where
one of the inputs could be zero, but I think
it's wrong: https://alive2.llvm.org/ce/z/dF7V6k

nsz shouldn't permit introducing a -0 result where
there wasn't one in the input here.

InstCombine: Handle minimumnum/maximumnum in SimplifyDemandedFPClass

InstCombine: Add baseline minimumnum/maximumnum SimplifyDemandedFPClass tests

InstCombine: Implement SimplifyDemandedFPClass for sqrt

InstCombine: Add baseline tests for sqrt SimplifyDemandedFPClass

InstCombine: Handle minimum/maximum in SimplifyDemandedFPClass

InstCombine: Add baseline test for SimplifyDemandedFPClass log handling

InstCombine: Handle fmul by -0 case in SimplifyDemandedFPClass

The fmul visitor handles this case as copysign and fneg.

InstCombine: Handle log/log2/log10 in SimplifyDemandedFPClass

InstCombine: Consider not-inf/nan context when simplifying fmul

Consider if the result can be nan, or if the inputs cannot
be infinity from the flag when trying to simplify fmul into
copysign.

InstCombine: Add baseline tests for minimum/maximum SimplifyDemandedFPClass handling

Remove redundant nan output check
