target-sparc: Cleanup "global" temporary allocation 

There are 6 temporaries that disas_sparc_insn relies on having been
allocated.  Now that they are no longer referenced across branches,
they need not be allocated as local temps.

Move the allocation/free of these temporaries to make it clear that
they are local to the translation of a single insn.
