Added a test case for it.
Also added run lines for the test case in r227566.

5d8bb5c7c5 [Bitcode] Diagnose errors instead of asserting from bad input 
Eventually we can make some of these pass the error along to the caller.

Reports a fatal error if:
We find an invalid abbrev record
We try to get an invalid abbrev number
We can't fill the current word due to an EOF

Fixed an invalid bitcode test to check for output with FileCheck

293d3deea3 Use report_fatal_error instead of llvm_unreachable, so we don't crash on user input
