currently have. Unit tests don't work well for everything; we should
always try to have a nondeterminism stress test running.

Clear out the landing pad to call site map for each function.
...
This isn't put into the 'clear()' method because the information needs to stick
around (at least for a little bit) after the selection DAG is built.

Mark tADDrSPi as having side effects again.
...
It really doesn't, but when r141929 removed the hasSideEffects flag from
this instruction, it caused miscompilations. I am guessing that it got
moved across a stack pointer update.
Also clear isRematerializable after checking that this instruction is
in fact never rematerialized in the nightly test suite.

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.

Add value numbers when spilling dead defs.
...
When spilling around an instruction with a dead def, remember to add a
value number for the def.
The missing value number wouldn't normally create problems since there
would be an incoming live range as well. However, due to another bug
we could spill a dead V_SET0 instruction which doesn't read any values.
The missing value number caused an empty live range to be created which
is dangerous since it doesn't interfere with anything.
This fixes part of PR11125.
