[ping] use REGNUM macros instead of hardcoded values in aarch64 PROBE_STACK reg definitions

[Olivier Hainque <hainque at adacore dot com>]

Hello,

Ping for one of the changes last proposed here:

  https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00761.html

Submitted separately as an attempt to facilitate the review
process.

Got access to a linux box, so in addition to the Ada testing
we do on cross aarch64-vxworks7, bootstrapped and regression
tested on aarch64-linux.


This one is just a simple use of REGNUM macros instead
of harcoded values in the definition of PROBE_STACK_FIRST_REG
and PROBE_STACK_SECOND_REG in aarch64.c.

OK to commit ?

Thanks in advance!

Olivier
