[PATCH] x86: Define macros for APX options

["H.J. Lu" <hjl.tools@gmail.com>]

Define following macros for APX options:

1. __APX_EGPR__: -mapx-features=egpr.
2. __APX_PUSH2POP2__: -mapx-features=push2pop2.
3. __APX_NDD__: -mapx-features=ndd.
4. __APX_PPX__: -mapx-features=ppx.
5. __APX_INLINE_ASM_USE_GPR32__: -mapx-inline-asm-use-gpr32.

They can be used to make assembly codes compatible with APX options.
Some use cases are:

1. When __APX_PUSH2POP2__ is defined, assembly codes should always align
the outgoing stack to 16 bytes.
2. When __APX_INLINE_ASM_USE_GPR32__ is defined, inline asm statements
should contain only instructions compatible with r16-r31.

	PR target/114587
	* config/i386/i386-c.cc (ix86_target_macros_internal): Define
	__APX_XXX__ for APX options.
