Hey,

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

Thanks,

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
