[AARCH64] Add missing entries in iterator vwcore

[Kugan <kugan dot vivekanandarajah at linaro dot org>]

Hi,

In "aarch64_get_lane<mode>" operand 0 is VEL, so  for %<vwcore>0,
iterator vwcore should (?) support all the modes in VEL.

Ran into following error with a local patch for an existing test case.
However it can also be reproduced with the attached test case.

fnction âfn1â:
t.c:25:1: internal compiler error: output_operand: invalid %-code
 }

Attached patch fixes this. Bootstrapped and regression tested for
aarch64-none-linux-gnu with no new regression. Is this OK for trunk?

Thanks,
Kugan
