New Revision: 138800

URL: http://llvm.org/viewvc/llvm-project?rev=138800&view=rev
Log:
If something goes wrong while emitting a function (eg: we come across
an unsupported feature) don't just skip output of other functions, since
otherwise GCC assertions will fire.  Instead just do the minimum to make
GCC happy, while not outputting any LLVM IR.
