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.

As discussed on the ml, backend tests need to be put in llvm/test/CodeGen/X86 as fast-isel tests using IR that is as close to what is generated here as possible.
The llvm tests will (re)added in a future commit
I will update PR24580 on this new plan
