4e68054b20 More closely follow libgcc, which has code after the `ret' instruction to
release the stack segment and reset the stack pointer. Place the code in its own
MBB to make the verifier happy.

81b2928d80 ARM addrmode5 represents the 'U' bit of the encoding backwards.
The disassembler needs to use the AM5 factory methods instead of just
building up the immediate directly.

1c062c24ab Fix -widen-vmovs liveness issues.
When widening a copy, we are reading a larger register that may not be
live.  Use an <undef> flag to tell the register scavenger and machine
code verifier that we know the value isn't defined.

We now widen:

  %S6<def> = COPY %S4<kill>, %D3<imp-def>

into:

  %D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill>

This also keeps the <kill> flag on %S4 so we don't inadvertently kill a
live value in %S5.

Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves
the <undef> flag when converting VMOVD to VORR.

142bd1a54e Move -widen-vmovs to ARMBaseInstrInfo::expandPostRAPseudo().
The VMOVS widening needs to look at the implicit COPY operands.  Trying
to dig out the COPY instruction from an iterator in copyPhysReg() is the
wrong approach.

The expandPostRAPseudo() hook gets to look at COPY instructions before
they are converted to copyPhysReg() calls.
