Hi all,
This patch replaces 15, 16, 7 and 8 in aarch64_class_max_nregs with the macro that they represent.
This should make the logic of that function easier to understand.
Bootstrapped and tested on aarch64.
Applying as obvious.

* config/aarch64/aarch64.c (aarch64_class_max_nregs):
Use UNITS_PER_VREG and UNITS_PER_WORD instead of their direct
values.
