    Add new argument NOSIDE to find_overload_match.

    This is a fix for PR c++/17132.
    If this new argument is set to EVAL_AVOID_SIDE_EFFECTS, then the object's
    memory will not be read while picking the best overload match.

    gdb/

        * eval.c: Update all calls to find_overload_match.
        * valarith.c: Likewise.
        (value_user_defined_cpp_op, value_user_defined_op): New
        argument NOSIDE.  Update all callers.
        * valops.c (find_overload_match): New argument NOSIDE.
        * value.h (find_overload_match): Update signature.

    gdb/testsuite

        * gdb.cp/pr17132.cc: New file.
        * gdb.cp/pr17132.exp: New file.
