<x86gprintrin.h>: Add pragma GCC target("general-regs-only")
1. Intrinsics in <x86gprintrin.h> only require GPR ISAs. Add
#if defined __MMX__ || defined __SSE__
#pragma GCC push_options
#pragma GCC target("general-regs-only")
#define __DISABLE_GENERAL_REGS_ONLY__
#endif
and
#ifdef __DISABLE_GENERAL_REGS_ONLY__
#undef __DISABLE_GENERAL_REGS_ONLY__
#pragma GCC pop_options
#endif /* __DISABLE_GENERAL_REGS_ONLY__ */
to <x86gprintrin.h> to disable non-GPR ISAs so that they can be used in
functions with __attribute__ ((target("general-regs-only"))).
2. When checking always_inline attribute, if callee only uses GPRs,
ignore MASK_80387 since enable MASK_80387 in caller has no impact on
callee inline.
