I agree with most of what Jim said. Except for the part that we maybe don't
have to fix the reload issue, when we fix usage of the uninitialized register
for piecewise struct initialization. The latter will fix this

The reload patch seems reasonable, though not very satisfying. It is only
disabling some optimizations within reload, and hence should be somewhat safe.
Though it is still a reload patch, and all reload pat

I have a patch for reload, which fixes the bug, when looking at the dumps.
At least now find_reg is used for the insn in question, which also evicts
