`--disassemble`/`--cdis` parses input bytes as decimal, 0bbin, 0ooct, or
0xhex. While the hexadecimal digit form is most commonly used, requiring
a 0x prefix for each byte (`0x48 0x29 0xc3`) is cumbersome.
Tools like xxd -p and rz-asm use a plain hex dump form without the 0x
prefix or space separator. This patch adds --hex to disassemble such hex
bytes with optional whitespace.
```
% rz-asm -a x86 -b 64 -d 4829c34829c4
sub rbx, rax
sub rsp, rax
% llvm-mc -triple=x86_64 --cdis --hex --output-asm-variant=1 <<< 4829c34829c4
.text
sub rbx, rax
sub rsp, rax
```

Add support for syntax highlighting assembly. The patch introduces new
RAII helper called WithMarkup that takes care of both emitting colors
and markup annotations. It makes adding markup easier and ensures colors
and annotations remain consistent.
This patch adopts the new helper in the AArch64 backend. If your backend
already uses markup annotations, adoption is as easy as using the new
MCInstPrinter::markup overload.

The comment moved is referring to the --output-asm-syntax flag rather
than the --print-imm-hex flag, but seems to have mistakenly been put
under the definition of that flag due to some misplaced line numbers on
phabricator.
Currently the filetype flag is not documented, and knowing the behavior
of this flag is fairly important for doing anything other than
disassembling to text assembly.
