Testing LLVM's relocation processing is good (as Lang pointed out to
me) and I think that's been preserved by my commit.

The problem came when we called the host OS's __register_frame or
whatever on the result. I think at that point it had a legitimate
expectation that we hadn't fed it nonsense (e.g. mismatched-endian
CIEs or even potentially non-DWARF frame info). It might have wanted
to parse the info and do some arcane preprocessing to speed up
handling, for example.

Cheers.

Tim.
