[stdlib] Make single-grapheme check debug-only
...
Because of the way grapheme breaking changes across updates to ICU and the Unicode standard, it may not even be legit to check this at all. It's certainly not unsafe to skip the check, so let's see if we can do that in release builds, as grapheme breaking is expensive.

[stdlib] Encode small Characters as UTF-16
...
This takes care of the standard library portion, but we need a new
BuiltinUTF16ExtendedGraphemeClusterLiteralConvertible protocol in order to
fully recover the performance of character literals.
Note that part of the character_literals.swift test is currently disabled. That
will need to be fixed before we can merge this work.

[sil-generic-specializer] Add @_semantics("optimize.sil.specialize.generic.partial.never") to disable partial specialization on functions
...
This new @_semantics is used to annotate some very big functions in the standard library. It reduced the code size of the stdlib by 2%.

Double-checking for CR-LF is redundant in

[stdlib] Grapheme break fast-paths for Cyrillic, Arabic, Hangul
...
Add in more grapheme break fast paths for scripts based on Cyrillic,
Arabic, or Hangul. Generates significant performance wins, similar to
those for the unihan fast paths.
While every extra check does slow down the runtime of
_internalExtraCheckGraphemeBreakBetween as currently implemented, I've
not found the performance cost to be relevant for workloads with
occasional mixed emoji contents, nor for workloads that his the
earlier checks. A pure Korean workload (currently the last check) does
pays a rather noticable price for the previous checks, but this is
only because the workload is now so greatly improved. Optimizing this
implementation is interesting future work, but not urgent.
