Summary:
The RegionGenerator traditionally kept a BlockMap that mapped from original
basic blocks to newly generated basic blocks. With the introduction of partial
writes such a 1:1 mapping is not possible any more, as a single basic block
can be code generated into multiple basic blocks. Hence, depending on the use
case we need to either use the first basic block or the last basic block.
This is intended to address the last four cases of incorrect code generation
in our AOSP buildbot and hopefully should turn it green.
