The main goal of the patchset is to move the ARM_FEATURE_VFP
test from outside of the disas_vfp_insn() to inside each of
the trans_* functions, so that we get the proper ISA check
for each case.

At the end of that, it is easy to eliminate all of the remaining
tests vs ARM_FEATURE_VFP* in favor of the preferred ISAR tests.

Finally, there are a couple of cleanups to vfp.decode to make
things a bit more legible.
