addps %xmm3, %xmm2
Saving a register and an instruction. The standard spiller already knows how to

ARM::tMOVgpr2gpr. But this check didn't change. As a result, we were getting

There is a test case, but unfortunately it's sensitive to random code changes.

During local stack slot allocation, the materializeFrameBaseRegister function
...
may be called. If the entry block is empty, the insertion point iterator will be
the "end()" value. Calling ->getParent() on it (among others) causes problems.
Modify materializeFrameBaseRegister to take the machine basic block and insert
the frame base register at the beginning of that block. (It's very similar to
what the code does all ready. The only difference is that it will always insert
at the beginning of the entry block instead of after a previous materialization
of the frame base register. I doubt that that matters here.)
