target/arm: Convert Neon 2-reg-scalar float multiplies to decodetree
Convert the float versions of VMLA, VMLS and VMUL in the Neon
2-reg-scalar group to decodetree.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

As noted in the comment on the WRAP_FP_FN macro, we could have
had a do_2scalar_fp() function, but for 3 insns it seemed
simpler to just do the wrapping to get hold of the fpstatus ptr.
(These are the only fp insns in the group.)
