<pre>MCJIT::finalizeLoadedModules() ignores the return value (and error argument)
from MemMgr->finalizeMemory(), which appears to be the only way that an error
code from mprotect() is propagated. mprotect() can fail for various reasons and
it would be good if clients of MCJIT could detect the problem and fail
gracefully.
