PPC: Fix TCG chunks that don't free their temps

Browse Source 
We want to make sure that every instruction cleans up after itself and
clears every temporary it allocated.

While checking whether this is already the case, I came across a few
cases where it isn't. This patch fixes every translation I found that
doesn't free their allocated temporaries.
