To report a new bug, please open a separate issue.

x86/x86_64

• _mm_shuffle_ps masks argument type is an u32 instead of an i32 (like for all other shuffle intrinsics), this is a bug in the Intel Intrinsics Guide, reported in _MM_SHUFFLE has incorrect return type #522
• _rdtsc returns a signed integer type instead of an unsigned one, this is a bug in the Intel Intrinsics Guide (https://software.intel.com/en-us/forums/intel-isa-extensions/topic/363747), reported in x86 _rdtsc has wrong return type #559
• _mm_pause does not require SSE2, but we initially did because the intel intrinsics guide says it is required. This is a bug in the Intel Intrinsics Guide: not reported yet. See _mm_pause should not require the SSE2 target feature #705
