Copy implicit defs (e.g. r0) when changing tBX_RET to tPOP_RET. This bug is

Thumb1 does not support dynamic stack realignment.
rdar://10288916 is tracking this fix.
In the past, instcombine and other passes were promoting alloca alignment past
the natural alignment, resulting in dynamic stack realignment. Lang's work now
prevents this from happening (LLVM commit r141599). Now that this really
shouldn't happen report a fatal error rather than silently generate bad code.

Attempt to fix dynamic stack realignment for thumb1 functions. It is in fact
useful if an optimization assumes the stack has been realigned. Credit to

Thumb1 ADD/SUB SP instructions are predicable in Thumb2 mode.
Add the predicate operand to the instructions. Update the back end
accordingly where the instructions are used. Restrict the SP operands
to actually only be SP, as otherwise these break assembly parsing for the
normal instruction variants.

Make tBX_RET and tBX_RET_vararg predicable.
The normal tBX instruction is predicable, so there's no reason the
pseudos for using it as a return shouldn't be. Gives us some nice code-gen
improvements as can be seen by the test changes. In particular, several
tests now have to disable if-conversion because it works too well and defeats
the test.

Refact ARM Thumb1 tMOVr instruction family.
Merge the tMOVr, tMOVgpr2tgpr, tMOVtgpr2gpr, and tMOVgpr2gpr instructions
into tMOVr. There's no need to keep them separate. Giving the tMOVr
instruction the proper GPR register class for its operands is sufficient
to give the register allocator enough information to do the right thing
directly.

Thumb1 register to register MOV instruction is predicable.
Fix a FIXME and allow predication (in Thumb2) for the T1 register to
register MOV instructions. This allows some better codegen with
if-conversion (as seen in the test updates), plus it lays the groundwork
for pseudo-izing the tMOVCC instructions.

Fix coordination for using R4 in Thumb1 as a scratch for SP restore.
The logic for reserving R4 for use as a scratch needs to match that for
actually using it. Also, it's not necessary for immediate <=508, so adjust
the value checked.

Implement frame unwinding information emission for Thumb1. Not finished yet because there is no way given the constpool index to examine the actual entry: the reason is clones inserted by constant island pass, which are not tracked at all! The only connection is done during asmprinting time via magic label names which is really gross and needs to be eventually fixed.
