If we failed to commit the buffer but did not die to a signal, the temp file would remain on disk on Windows. Having an open file mapping and file handle prevents the file from being deleted. I am choosing not to add an assertion of success on the temp file removal, since virus scanners and other environmental things can often cause removal to fail in real world tools. Also fix more temp file leaks in unit tests. llvm-svn: 280445
