[AArch64, PATCH 1/5] Improve MOVI handling (Change interface of aarch64_simd_valid_immediate)

["Ian Bolton" <ian dot bolton at arm dot com>]

(This patch is the first of five, where the first 4 do some clean-up and
the last fixes a bug with scalar MOVI.  The bug fix without the clean-up
was particularly ugly!)


This one is pretty simple - just altering an interface, so we can later
remove an unnecessary wrapper function.


OK for trunk?

Cheers,
Ian
