d174fe0ec3 CR registers are not used by this "target"

0a37960d32 these registers don't belong to any register classes, so don't mark them 
as callee save.  They can never be generated by the compiler.

f13befb456 Make the JIT default to the DAG isel instead of the pattern isel, like LLC. 
The Pattern isel has some strange memory corruption issues going on. :(

This should have been converted over anyway, but it got forgotten somehow
when switching to the dag isel.

d145a61f8f Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal mask 
on setjmp calls and restores it on longjmp calls (both of which require syscalls).

This makes the calls REALLY slow.  Use _setjmp/_longjmp instead.  This speeds up
hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC.

f4e6c3a69b Completely rewrite 'correct' eh support. This changes how setjmp insertion 
is performed so it is only at most once per function that contains an invoke
instead of once per invoke in the function.  This patch has the following perks:

1. It fixes PR631, which complains about slowness.
2. If fixes PR240, which complains about non-volatile vars being live across
   setjmp/longjmps.
3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not
   forcing the jmpbufs to always be 8-bytes off the alignment of the structure.
4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us
   now about 4% faster than GCC.

Further improvements are also possible.
