<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.

gcc/

	PR target/99744
	* config/i386/i386.c (ix86_can_inline_p): Ignore MASK_80387 if
	callee only uses GPRs.
	* config/i386/ia32intrin.h: Revert commit 5463cee2770.
	* config/i386/serializeintrin.h: Revert commit 71958f740f1.
	* config/i386/x86gprintrin.h: Add
	#pragma GCC target("general-regs-only") and #pragma GCC pop_options
	to disable non-GPR ISAs.

gcc/testsuite/

	PR target/99744
	* gcc.target/i386/pr99744-3.c: New test.
	* gcc.target/i386/pr99744-4.c: Likewise.
	* gcc.target/i386/pr99744-5.c: Likewise.
	* gcc.target/i386/pr99744-6.c: Likewise.
