[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. Differential Revision: https://reviews.llvm.org/D24825 llvm-svn: 282581

// CHECK-LABEL: test_mm256_nmsub_ps
[X86] Reduce the number of FMA builtins needed by the frontend by adding negates to operands of the fmadd and fmaddsub builtins. The backend should be able to combine the negates to create fmsub, fnmadd, and fnmsub. faddsub converting to fsubadd still needs work I think, but should be very doable. This matches what we already do for the masked builtins. This only covers the packed builtins. Scalar builtins will be done after FMA4 is fixed. llvm-svn: 317873

[X86] Lowering FMA intrinsics to native IR (Clang part) This patch replaces all packed (and scalar without rounding mode) fused intrinsics with fmadd/fmaddsub variations.
