As has been spotted at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01289.html
we check the __AARCH64EB__ macro for aarch64 big-endian
detection in config/cpu/aarch64/opt/ext/opt_random.h.
That works just fine with GCC but the standardised ACLE[1] macro
for that purpose is __ARM_BIG_ENDIAN so there is a possibility
that non-GCC compilers that include this header are not aware
of this predefine.

So this patch changes the use of __AARCH64EB__ to
the more portable __ARM_BIG_ENDIAN.

Tested on aarch64-none-elf and aarch64_be-none-elf.

In this bug we ICE when checking REGNO_OK_FOR_INDEX_P on arm during pre-IRA scheduling.
This is because REGNO_OK_FOR_INDEX_P ends up checking the reg_renumber array.
Before IRA reg_renumber is NULL and thus we segfault.

The fix is to guard the use of reg_renumber in the logic in TEST_REGNO in arm.h.
On aarch64, for example, we also guard against the reg_renumber == NULL case.
This fixes the ICE. I also remove the part of the comment that muses on when reg_renumber
is available as with this patch it should now be safe to use at any point.

Bootstrapped and tested on arm-none-linux-gnueabihf.
