Smallest test cases are test/ExecutionEngine/MCJIT/{eh-sm-pic,eh-lg-pic}.ll

Both fail the same way:

 /home/abuild/rpmbuild/BUILD/llvm/stage2/./bin/lli -use-mcjit
-relocation-model=pic -code-model=small
/home/abuild/rpmbuild/BUILD/llvm/test/ExecutionEngine/MCJIT/eh-sm-pic.ll
 --
 Exit Code: 134

 Command Output (stderr):
 --

Note that this clang is hardcoded to use libc++ (-stdlibc=libc++). Is this
good enough?

Thanks!
