7bc3969cea Add APInt interfaces to APFloat (allows directly
access to bits).  Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling 
(untested, probably does not work).

init_trampoline.  There is now only one
trampoline intrinsic.

3c6a8b2814 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.

4715ccb29c 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.

8c57e70f93 Add support for having different alignment for objects on call frames.

8 byte alignment. Implement that.

86f367a6b7 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.)
