The jump table was being generated before the end label for exception handling

was generated. This caused code like this:
## The asm code for the function

Leh_func_end11: ## <---now in the wrong section!
The `Leh_func_end11' would then end up in the wrong section, causing the
resulting EH frame information to be wrong:
__ZL11CheckRightsjPKcbRbRP6NSData.eh:
.set Lset500eh,Leh_frame_end11-Leh_frame_begin11
.long Lset500eh ; Length of Frame Information Entry
Leh_frame_begin11:
.long Leh_frame_begin11-Leh_frame_common
.long Leh_func_begin11-.
.set Lset501eh,Leh_func_end11-Leh_func_begin11
.long Lset501eh ; FDE address range
`Lset501eh' is now something huge instead of the real value.
The X86 back-end generates the jump table after the EH information is
emitted. Do the same here.

Generalize LCSSA to handle loops with exits with predecessors outside

the loop. This is needed because with indirectbr it may not be possible
for LoopSimplify to guarantee that all loop exit predecessors are
inside the loop. This fixes PR5437.
LCCSA no longer actually requires LoopSimplify form, but for now it
must still have the dependency because the PassManager doesn't know
how to schedule LoopSimplify otherwise.

Fix an issue where the ordering of blocks within a function could lead to different constraint
...
graphs being produced. The cause was that we were incorrectly marking sigma instructions as
processed after handling the sigma-specific constraints for them, potentially neglecting to
process them as normal instructions as well.
Unfortunately, the testcase that inspired this still doesn't work because of a bug in the solver,
which is next on the list to debug.

Teach an instcombine to not pull trunc instructions through PHI nodes
