[PATCH 1/3] match: Don't use for loop for maybe_cmp

[Andrea Pinski]

This does not change the output of genmatch (except for line numbers)
but it simplifies the pattern in match.pd for easier understanding.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

        * match.pd (maybe_cmp): Use tcc_comparison directly instead
        of for loop.
