Re: [AArch64][PATCH 1/2] Add support for RAS instruction ESB.

Hello,

The ARMv8.2 RAS extension adds a new barrier instruction ESB as an alias and the
preferred form of HINT 16.

This patch adds an architectural feature flag for the RAS extension and includes
it in the features selected enabled by -march=armv8.2-a. It also adds the ESB
instruction, making it available whenever the RAS feature is enabled.

I forgot to say that this patch depends on the ARMv8.1/ARMv8.2 feature flag clean up
