Potential self-hosting failure

[John Brawn via cfe-commits]

I've now tracked this down to a problem with LEApcrel rematerialization
where the rematerialized LEApcrel can address a different literal pool
to the original. I've raised https://bugs.llvm.org/show_bug.cgi?id=33074

This is actually a bug that already existed before my patches, but because
my patches made LEApcrel be rematerialized in more situations they made it
more likely to trigger the bug. I'll continue looking into this to see if
I can figure out how to fix it.
