intrinsics when compiled for 32-bit mode.
All the command lines are for 64-bit mode, but sometimes I compile
the tests in 32-bit mode to see what assembly we get and we need
to skip these to do that.

Remove popcnt feature flag from _popcnt32/_popcnt64 and move to ia32intrin.h to match gcc
gcc and icc both implement popcntd and popcntq which we did not. gcc doesn't seem to require a feature flag for the _popcnt32/_popcnt64 spelling and will use a libcall if its not supported.

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.

The Intel manual documents both an unsigned form (_mm_popcnt_u32)
and a signed form (_popcnt32) of the intrinsic. Add the missing signed form.

enabled, but can be disabled separately. Move popcnt intrinsics to popcntintrin.h to match gcc.
