[m-dev.] trivial diff: fix infinite_recursion test case failure

[Fergus Henderson]

This fixes a test case failure for MCFLAGS=-O1 or lower.

----------

Estimated hours taken: 0.25

tests/warnings/Mmakefile:
	Pass `--excess-assign --common-struct' to mmc for the
	infinite_recursion test case, since some of the warnings
	for infinite recursion don't show up at lower optimization
	levels unless those optimizations are explicitly enabled.
