[patch] i386: Remove unused macros.


Hi,

Attached is a patch to remove unused macros.

Strictly speaking, RET is used once, but it's more trouble than it is
worth.

Bootstrapped on i686-pc-linux-gnu.  OK to apply?

	* config/i386/i386.h (NON_STACK_REG_P, REGNO_OK_FOR_SIREG_P,
	REGNO_OK_FOR_DIREG_P, REWRITE_ADDRESS, ASM_OPERAND_LETTER,
	RET, AT_SP): Remove.
	* config/i386/i386.md (*sse_prologue_save_insn): Use return
	instead of RET.
