[PATCH][gas][AArch64] Add support for Cortex-A72


The Cortex-A72 is an ARMv8 core with the same architectural features as the Cortex-A57. This patch adds support to GAS for the command line option -mcpu=cortex-a72 with the same effect as the -mcpu=cortex-a57 option, only the name being different.

Tested check-gas with aarch64-none-linux-gnu, no failures. Tested the new cpu option from the command line.
Ok for trunk?
