The personality function on Darwin needs a global stub. We then refer to
...
that global stub instead of doing the ".set" thingy we were doing before.

It's not safe to rematerialize MOV32r0 etc. by simply cloning the original
...
instruction. These are implemented with xor which will modify the conditional
code. They should be rematerialized as move instructions.

Next round of APFloat changes.
...
Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double. Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
