Minor tweak to the branch selector. When emitting a two-way branch, and if
...
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch. For example, emit this:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
ble cr0, LBBl29_z__44
b LBBl29_z__48 *** NOT PART OF LOOP
Instead of:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
bgt cr0, LBBl29_z__48 *** PART OF LOOP!
b LBBl29_z__44
The former sequence has one fewer dispatch group for the loop body.

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.

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.
