Hi All,

The build attribute number for Armv8.4-A is currently incorrectly set to that of Armv8-M.
This patch fixes that by setting it as part of the Armv8-A family and adds a test for it.

Regtested on cross build:

 * arm-none-eabi
 * armeb-none-eabi

Bootstrapped and regtested on:

 * arm-none-eabi
 * arm-none-eabi (64 bit host)

and no issues.

Ok for master?

And also requesting permission to backport to binutils 2.30.

	* config/tc-arm.c (cpu_arch_ver): Renumber ARM_ARCH_V8_4A.
	* testsuite/gas/arm/attr-march-armv8_4-a.d: New.
