OK, thanks.

Think you've posted enough patches now to apply for svn write access.
Will follow up off-list.

[AArch64, SVE] Fix vectorized FP converts

[Alejandro Martinez Vicente]

Hi,

Some of the narrowing/widening FP converts were missing from SVE. I fixed most
of them, so they can be vectorized. The ones missing are int64->fp16 and
fp16->int64.

I extended the tests to cover the cases that were missing.

I validated the patch with self-checking and running the new SVE tests on an
SVE emulator.
