Hey,
Updated the previous patch by rebasing with latest master and also
adding the missing "testsuite/gas/aarch64/cpu-cortex-x4.d" file.
Thanks,
Saurabh

Hey,
This patch adds support for the Cortex-X4 CPU to binutils.
Regression testing for aarch64-none-elf target and found no regressions.
Okay for binutils-master? I don't have commit access so if it looks
okay, could someone please help me commit this?
Thanks,
Saurabh
