[AArch64] Add BRB IALL and BRB INJ instructions

BRB IALL: Invalidate the Branch Record Buffer
BRB INJ: Branch Record Injection into the Branch Record Buffer

Parser changes based on work by Simon Tatham.

These are two-word mnemonics. The assembly parser works by special-casing
the mnemonic in order to parse the second word as a plain identifier token.

Reapply multiple "[clang][cli]" patches

This reverts 7ad666798f12 and 1876a2914fe0 that reverted:

741978d727a4 [clang][cli] Port CodeGen option flags to new option parsing system
383778e2171b [clang][cli] Port LangOpts option flags to new option parsing system
aec2991d083a [clang][cli] Port LangOpts simple string based options to new option parsing system
95d3cc67caac [clang][cli] Port CodeGenOpts simple string flags to new option parsing system
27b7d646886d [clang][cli] Streamline MarshallingInfoFlag description
70410a264949 [clang][cli] Let denormalizer decide how to render the option based on the option class
63a24816f561 [clang][cli] Implement `getAllArgValues` marshalling

Commit 741978d727a4 accidentally changed the `Group` attribute of `g[no_]column_info` options from `g_flags_Group` to `g_Group`, which changed the debug info options passed to cc1 by the driver.

Similar change was also present in 383778e2171b, which accidentally added `Group<f_Group>` to `f[no_]const_strings` and `f[no_]signed_wchar`.

This patch corrects all three accidental changes by replacing `Bool{G,F}Option` with `BoolCC1Option`.
