[ACTIVITY]
Upstream reviews for LLD. Trying to be more proactive here now that
there are fewer maintainers.

[TCWG-1420] Initial investigation into some proposed linker
enhancements for embedded systems
- Mostly features already implemented in proprietary linkers such as
AT and an equivalent to .any.
- Completed initial investigation with links to TI/IAR documentation,
binutils discussions.
- Some thoughts on which of the features might be implemented cleanly
enough to be upstreamed.

Pinged llvm-mc subtarget reviews (no response)

Spent some more time investigating a tiny-code model for AArch64 in an
attempt to teach myself more about LLVM.
