This still crashes:

./bin/llc  /home/espindola/llvm/llvm/test/CodeGen/X86/asm-invalid-register-class-crasher.ll
 -mtriple=i386-apple-darwin

llc: /home/espindola/llvm/llvm/include/llvm/Target/TargetLowering.h:321:
virtual const llvm::TargetRegisterClass
*llvm::TargetLoweringBase::getRegClassFor(llvm::MVT) const: Assertion
`RC && "This value type is not natively supported!"' failed.

Looks like it is not normally noticed because there is an error in the
RUN line giving llc multiple positional arguments.
