Describe the bug

s_has_vpclmulqdq() is not checking the correct bit to detect VPCLMULQDQ.
According to the documentation it is bit 10. (code is checking bit 20).

Input Output
EAX=07H, ECX=0 ECX[bit 10] VPCLMULQDQ
EAX=07H, ECX=0 EBX[bit 16] AVX512F
EAX=07H, ECX=0 EBX[bit 31] AVX512VL

Expected Behavior

s_has_vpclmulqdq() should return TRUE if the CPU supports it.

Current Behavior

s_has_vpclmulqdq() returns FALSE incorrectly.

Reproduction Steps

call s_has_vpclmulqdq() on any modern IA system.
