[tree-ssa] [PATCH] Clean up tree-ssa-phiopt.c a little

[Andrew Pinski <pinskia at physics dot uc dot edu>]

I wanted to implement another optimization in tree-ssa-phiopt.c but the 
code
was hard to add another so I moved the current optimization into another
function which I called conditional_replacement (this function name can 
be
changed, I am not attached to it at all).

OK? Bootstrapped on powerpc-apple-darwin with no regressions and the
optimization still happens.

Thanks,
Andrew Pinski
