x86/runtime-const: Introduce runtime_const_mask_32()
Futex hash computation requires a mask operation with read-only after
init data that will be converted to a runtime constant in the subsequent
commit.
Introduce runtime_const_mask_32 to further optimize the mask operation
in the futex hash computation hot path.
[ prateek: Broke off the x86 chunk, commit message. ]
