[PATCH] D59567: [X86] Add __popcntd and __popcntq to ia32intrin.h to match gcc and icc. Remove popcnt feature flag from _popcnt32/_popcnt64 and move to ia32intrin.h to match gcc

+/// This intrinsic corresponds to the <c> POPCNT </c> instruction.

----------------
Change this as we don't require POPCNT any more?
