Subject: [PATCH 1/5] Fix for changed code at the end of AllocaIP.
Some of the OpenMP code can change the instruction pointed at by
the insertion point. This leads to an assert in the compiler about
BB->getParent() and IP->getParent() not matching or something like
that.
The fix is to rebuild the insertionpoint from the block, rather
than use builder.restoreIP.
Also, move some of the alloca generation, rather than skipping back
and forth between insert points (and ensure all the allocas are done
before their users are created).
A simple test, mainly to ensure the minimal reproducer doesn't fail
to compile in the future is also added.
