The 'lax' argument to find_overload_match is not used. I do not know
the history as to why this argument is present, but the attached patch
removes this argument.

Tested by building on x86_64 linux.

2013-01-25  Siva Chandra Reddy  <sivachandra@google.com>

        * valops.c (find_overload_match): Remove unused argument
'lax'.
        * value.h: Remove unused argument 'lax' from the declaration
of
        find_overload_match.
        * eval.c (value_subexp_standard): Do not pass a 'lax' argument
        to find_overload_match.
        * valarith.c (value_user_defined_cpp_op): Do not pass a 'lax'
        argument to find_overload_match.
