Add InlineAsmDiagnosticHandler for bitcode input 

Summary:
This patch installs an InlineAsmDiagnosticsHandler to avoid the crash
report when the input is bitcode and the bitcode contains invalid inline
assembly. The handler will simply print the same error message that will
print from the backend.

Add CHECK in test-case
