Mitch Phillips 850defb861 Add assembler plumbing for sanitize_memtag 
Extends the Asm reader/writer to support reading and writing the
'.memtag' directive (including allowing it on internal global
variables). Also add some extra tooling support, including objdump and
yaml2obj/obj2yaml.

Test that the sanitize_memtag IR attribute produces the expected asm
directive.

Uses the new Aarch64 MemtagABI specification
(https://github.com/ARM-software/abi-aa/blob/main/memtagabielf64/memtagabielf64.rst)
to identify symbols as tagged in object files. This is done using a
R_AARCH64_NONE relocation that identifies each tagged symbol, and these
relocations are tagged in a special SHT_AARCH64_MEMTAG_GLOBALS_STATIC
section. This signals to the linker that the global variable should be
tagged.
