* 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.
