X86 Intrinsics: _bit_scan_forward should not be under #ifdef __RDRND__
Summary:
The _bit_scan_forward and _bit_scan_reverse intrinsics were accidentally
masked under the preprocessor checks that prune intrinsics definitions for the
benefit of faster compile-time on Windows. This patch moves the
definitons out of that region.
