        * 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.
