[PATCH] [AArch64] Add support for the Samsung Exynos M1 processor

[Evandro Menezes <e.menezes@samsung.com>]

[-- Attachment #1: Type: text/plain, Size: 279 bytes --]

The Samsung Exynos M1 implements the ARMv8 ISA and this patch adds support
to GAS for it through the -mcpu command-line option.

The patch was tested on aarch64-unknown-linux-gnu without new failures.

OK for trunk?
