Fix a subtle bug in "return;" generation which caused us to miss
a return in one case.  Instead of sprinking return handling code
throughout the asmprinter generator, just treat it like any other
normal statement.

hoist the call to processDebugLoc out of the generated
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

Change these tests to feed the assembly files to opt directly, instead
of using llvm-as, now that opt supports this.

llvm-as is no longer needed here, now that opt can read assembly
files directly.

Re-apply r80926, with fixes: keep the domtree informed of new blocks
that get created during loop unswitching, and fix SplitBlockPredecessors'
LCSSA updating code to create new PHIs instead of trying to just move
existing ones.

Also, optimize Loop::verifyLoop, since it gets called a lot. Use
searches on a sorted list of blocks instead of calling the "contains"
function, as is done in other places in the Loop class, since "contains"
does a linear search. Also, don't call verifyLoop from LoopSimplify or
LCSSA, as the PassManager is already calling verifyLoop as part of
LoopInfo's verifyAnalysis.

Add NEON 'laned' operations. This fixes another bunch of gcc testsuite fails and

When emitting a label for a PostCall safe point, the machine
instruction to insert before can be end(). getDebugLoc on
end() returns an invalid value, therefore use the debug
loc of the call instruction, and give it to InsertLabel.
