Subject: [PATCH] Extend MVE patterns

Hello,

MVE currently can be applied on insns that are of the form of:
x = x + something
This patch extend MVE to support also insns of the form:
x = something + x.   This form can appears when PPC built-in function
builtin_madd is expanded to RTL.

Bootstrapped and tested on ppc.

OK for mainline?

Thanks,
Revital

        * loop-unroll.c (var_to_expand): New field to support also
        insns of the form x = something + x.
        (analyze_insn_to_expand_var): Use it.
        (expand_var_during_unrolling): Likewise.
