[binutils][aarch64] SVE2 feature extension flags.

Include all feature flag macros.

The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.

Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.

Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

gas/ChangeLog:

2019-05-09  Matthew Malcomson  <matthew.malcomson@arm.com>

	* config/tc-aarch64.c: Add command line architecture feature flags
	"sve2", "sve2-sm4", "sve2-aes", "sve2-sha3", "bitperm".
	* doc/c-aarch64.texi: Document new architecture feature flags.
