Subject: * sysdeps/i386/asm-syntax.h (R, MEM, MEM_DISP, MEM_INDEX,

INSN1, INSN2, TEXT, GLOBL): Remove macros.
(ALIGN): Cleanup surrounding conditionals.
	* sysdeps/i386/addmul_1.S: Replace asm-syntax macros with gas syntax.
	Call ENTER/LEAVE macros.
	* sysdeps/i386/mul_1.S: Replace asm-syntax macros with gas syntax.
	* sysdeps/i386/submul_1.S: Likewise.

	* sysdeps/i386/i586/addmul_1.S: Replace asm-syntax macros with gas
	syntax.  Define & use symbolic argument stack offsets.  Call
	ENTER/LEAVE macros.
	* sysdeps/i386/i586/mul_1.S: Likewise.
