Add support for the llvm.unwind intrinsic, which we codegen to just do an abort
...
until we implement unwinding.
Add support for the invoke instruction, which codegens just like a call with
a branch after it.
The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine. Programs that unwind will abort until
we get unwind support.

Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic
call which causes llc & lli to core-dump.
Add a sort-of treatment of cast double to ulong. I am not really sure
what a user should expect to see upon casting a negative FP value to
unsigned long long. But with what is given here, I was able to write
a program that could cast -123.456 to ulong and back and get -123.0,
which seems like a step in the right direction. GCC seems to give you
0. I don't know if I'd consider that useful.
These cases were coming up in GNU coreutils-5.0.

This avoid generating a register to hold C, which in turn speeds up the
register allocator by a lot: ~9% on 164.gzip and ~17% on 256.bzip2. This
also speeds up other passes. This also speeds up execution of the program
marginally, and makes the asm much easier to read. :)
