2017-07-24  Daniel Santos  <daniel.santos@pobox.com>

	PR testsuite/80759
	* config.host: include i386/t-msabi for darwin and solaris.
	* config/i386/i386-asm.h
	(ELFFN): Rename to FN_TYPE.
	(FN_SIZE): New macro.
	(FN_HIDDEN): Likewise.
	(ASMNAME): Likewise.
	(FUNC_START): Rename to FUNC_BEGIN, use ASMNAME, replace .global with
	.globl.
	(HIDDEN_FUNC): Use ASMNAME and .globl instead of .global.
	(SSE_SAVE): Convert to cpp macro, hard-code offset (always 0x60).
	* config/i386/resms64.S: Use SSE_SAVE as cpp macro instead of gas
	.macro.
	* config/i386/resms64f.S: Likewise.
	* config/i386/resms64fx.S: Likewise.
	* config/i386/resms64x.S: Likewise.
