New Revision: 46706

URL: http://llvm.org/viewvc/llvm-project?rev=46706&view=rev
Log:
Crashed the new type legalizer.  Not likely to catch
any bugs in the future since to get the crash you also
need hacked in fake libcall support (which creates odd
but legal trees), but since adding it doesn't hurt...
Thanks to Chris for this ultimately reduced version.
