Made -Xfatal-warnings less immediately fatal.

Instead of changing warnings to errors mid-stream, at the end of
a run I check for condition "no errors, some warnings, and fatal
warnings" and then generate an error at that point.  This is
necessary to test for some warnings which come from later stages.
