Uriel Korach 3fba3c3b0c [X86] [PATCH] [intrinsics] Lowering X86 ABS intrinsics to IR. (clang)
This patch, together with a matching llvm patch (https://reviews.llvm.org/D37693), implements the lowering of X86 ABS intrinsics to IR.

Sanjay Patel e795daa55e [x86] these aren't the undefs you're looking for (PR32176)
x86 has undef SSE/AVX intrinsics that should represent a bogus register operand. 
This is not the same as LLVM's undef value which can take on multiple bit patterns.

There are better solutions / follow-ups to this discussed here:
https://bugs.llvm.org/show_bug.cgi?id=32176
...but this should prevent miscompiles with a one-line code change.

Simon Pilgrim 698528d83b [X86][AVX512] Replace lossless i32/u32 to f64 conversion intrinsics with generic IR
Both the (V)CVTDQ2PD (i32 to f64) and (V)CVTUDQ2PD (u32 to f64) conversion instructions are lossless and can be safely represented as generic __builtin_convertvector calls instead of x86 intrinsics without affecting final codegen.

This patch removes the clang builtins and their use in the headers - a future patch will deal with removing the llvm intrinsics.

This is an extension patch to D20528 which dealt with the equivalent sse/avx cases.

Craig Topper 5e0709d60b [AVX-512] Replace masked dword and qword variable shift builtins with unmasked builtins and a select.

Craig Topper 1a44193afd [AVX-512] Convert the rest of the masked shift by immediate and by single element builtins over to the newly added unmasked builtins and a select.
This should also fix PR30691 since the new builtins are handled like the legacy builtins in the backend.

Elad Cohen b107a22afb [X86] Remove the mm_malloc.h include guard hack from the X86 builtins tests
The X86 clang/test/CodeGen/*builtins.c tests define the mm_malloc.h include
guard as a hack for avoiding its inclusion (mm_malloc.h requires a hosted
environment since it expects stdlib.h to be available - which is not the case
in these internal clang codegen tests).
This patch removes this hack and instead passes -ffreestanding to clang cc1.
