Peter Maydell 524b54bc7b target/arm: Convert Neon 3-same-fp size field to MO_* in decode
In the Neon instructions, some instruction formats have a 2-bit size
field which corresponds exactly to QEMU's MO_8/16/32/64. However the
floating-point insns in the 3-same group have a 1-bit size field
which is "0 for 32-bit float and 1 for 16-bit float". Currently we
pass these values directly through to trans_ functions, which means
that when reading a particular trans_ function you need to know if
that insn uses a 2-bit size or a 1-bit size.

Move the handling of the 1-bit size to the decodetree file, so that
all these insns consistently pass a size to the trans_ function which
is an MO_8/16/32/64 value.

In this commit we switch over the insns using the 3same_fp and
3same_fp_q0 formats.
