Implement the following PowerISA v3.1 instructions:
xxmfacc: VSX Move From Accumulator
xxmtacc: VSX Move To Accumulator
xxsetaccz: VSX Set Accumulator to Zero
The PowerISA 3.1 mentions that for the current version of the
architecture, "the hardware implementation provides the effect of ACC[i]
and VSRs 4*i to 4*i + 3 logically containing the same data" and "The
Accumulators introduce no new logical state at this time" (page 501).
For now it seems unnecessary to create new structures, so this patch
just uses ACC[i] as VSRs 4*i to 4*i+3 and therefore move to and from
accumulators are no-ops.

fsel doesn't change FPSCR and CR1 is handled by gen_set_cr1_from_fpscr,
so helper_fsel doesn't need the env argument and can be declared with
TCG_CALL_NO_RWG_SE. We also take this opportunity to move the insn to
decodetree.

Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.
This can help to make some code independent from qemu too.
gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

were reordered to better match the PowerISA description. The same macro
is used to declare xvmadd* helpers, but the translation macro of these
