Subject: Fix function signature for rust_eh_personality

While cg_llvm is very lax about mismatched function signatures, cg_clif
will crash when there is any mismatch. It could be turned into an error,
but without Cranelift changes can't just be ignored.

Subject: Fix a bunch of missing unwinder related definitions

cg_llvm likely just optimizes out their references for these tests, but
cg_clif doesn't and would thus give a linker error.
