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.
