Michael Kuperstein beae026738 [X86] Add signed aliases for popcnt intrinsics 
The Intel manual documents both an unsigned form (_mm_popcnt_u32)
and a signed form (_popcnt32) of the intrinsic. Add the missing signed form.

Craig Topper 1de8348db7 Add popcnt feature flag to match gcc. This flag is implied when sse42 is enabled, but can be disabled separately. Move popcnt intrinsics to popcntintrin.h to match gcc.
