Especially if it is -O0 only, I don't see why you think so. Just dg-skip-if
it for -O1+ if you believe it is unreliable for some reason, but if you
look at the parameter value after the prologue, not showing the right value
at -O0 would be a serious bug everywhere. Having some GDB testcase also
doesn't hurt, but having it in GCC testsuite has significant advantages over
that, most GCC developers don't run GDB testsuite after any changes they do.
