Mostyn Bramley-Moore 46000a1244 [jumbo] fix arm64 builds 
Previously instructions-arm64.h was alternatively defining or declaring
some constants based on whether or not ARM64_DEFINE_FP_STATICS was defined,
and it was assumed that exactly one file would include this header with
the macro defined.

In jumbo builds, the header guards in instructions-arm64.h meant that the
resulting state of the header file would be whichever of the two cases
that appeared first in the compilation unit.  This would cause multiple
definitions in some cases and no definitions in some other cases (or if
you were really lucky, it would work out ok).

Let's move these constants to a separate source file temporarily, to be
excluded from jumbo compilation units.  This code should eventually be
replaced with a cleaner solution.
