Attachment: bug1377058-cgc-failure

The problem is that any test that sets the maximum heap size with code like:

  gcparam("maxBytes", gcparam("gcBytes") + 1024);

can potentially cause an unhandlable OOM crash.  This is rare and seems to be nondeterministic.

The patch adds the 'allow-unhandlable-oom' flag to jit-tests which have this code pattern.
