Fix double renaming bug in stack coloring pass
The stack coloring pass renumbered frame indexes with a loop of the form:
for each frame index FI
for each instruction I that uses FI
for each use of FI in I
rename FI to FI'
This caused problems if an instruction used two frame indexes F0 and F1
and if F0 was renamed to F1 and F1 to F2. The first time we visited the
instruction we changed F0 to F1, then we changed both F1s to F2.
In other words, the problem was that SSRefs recorded which instructions
used an FI, but not which MachineOperands and MachineMemOperands within
that instruction used it.
This is easily fixed for MachineOperands by walking the instructions
once and processing each operand in turn. There's already a loop to
do that for dead store elimination, so it seemed more efficient to
fuse the two at the block level.
MachineMemOperands are more tricky because they can be shared between
instructions. The patch handles them by making SSRefs an array of
MachineMemOperands rather than an array of MachineInstrs. We might end
up processing the same MachineMemOperand twice, but that's OK because
we always know from the SSRefs index what the original frame index was.

[SystemZ] Clean up register scavenging code
SystemZ wants normal register scavenging slots, as close to the stack or
frame pointer as possible. The only reason it was using custom code was
because PrologEpilogInserter assumed an x86-like layout, where the frame
pointer is at the opposite end of the frame from the stack pointer.
This meant that when frame pointer elimination was disabled,
the slots ended up being as close as possible to the incoming
stack pointer, which is the opposite of what we want on SystemZ.
This patch adds a new knob to say which layout is used and converts
SystemZ to use target-independent scavenging slots. It's one of the pieces
needed to support frame-to-frame MVCs, where two slots might be required.
The ABI requires us to allocate 160 bytes for calls, so one approach
would be to use that area as temporary spill space instead. It would need
some surgery to make sure that the slot isn't live across a call though.
I stuck to the "isFPCloseToIncomingSP - ..." style comment on the
"do what the surrounding code does" principle. The FP case is already
covered by several Systemz/frame-* tests, which fail without the
PrologueEpilogueInserter change, so no new ones are needed.

InstCombine: Reimplementation of visitUDivOperand
This transform was originally added in r185257 but later removed in
r185415. The original transform would create instructions speculatively
and then discard them if the speculation was proved incorrect. This has
been replaced with a scheme that splits the transform into two parts:
preflight and fold. While we preflight, we build up fold actions that
inform the folding stage on how to act.

Removed extension in [unordered_][multi]map which allowed one to emplace using just an argument for the key, as opposed to using piecewise_construct. However a bug report exposed that this created an unfortunate ambiguity. People who are currently using the extension will be notified the next time they compile, and will have to change to using piecewise_construct. There are no ABI issues with the removal of this extension. This fixes llvm.org/bugs/show_bug.cgi?id=16542

This implements a proper PPCAsmBackend::writeNopData routine
