re PR middle-end/70245 (Miscompilation of ICU on i386 with atom tuning starting with r227382)

	PR target/70245
	* rtl.h (replace_rtx): Add ALL_REGS argument.
	* rtlanal.c (replace_rtx): Likewise.  If true, use REGNO
	equality and assert mode is the same, instead of just rtx pointer
	equality.
	* config/i386/i386.md (mov + arithmetics with load peephole): Pass
	true as ALL_REGS argument to replace_rtx.
