[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

Canonicalize some of the x86 builtin tests and either remove or comment about optimization options. llvm-svn: 250271

// FIXME: This test currently depends on optimization - it should be rewritten to avoid it.
Make the byte-shift SSE intrinsics emit vector shuffles which we know the backend can handle. Also removed unused builtins. Original patch by Andrea Di Biagio! Reviewers: craig.topper, nadav Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D7199 llvm-svn: 228481
