ebdd5e6d98 [string] Fast-path for small string comparison 
Promote small-string to small-string comparison into the fast path for
equality and less-than.

Small ASCII strings that are not binary equal do not compare equal,
allowing us to early exit. Small ASCII strings otherwise compare
lexicographically, which we can call prior to jumping through a few
intermediaries.

0661de22a2 [stdlib]Un-revert string comparison (#14694) 
Restore (un-revert) sting comparison, with fixes

More exhaustive testing of opaque strings, which consistently reproduces prior sporadic failure. Shims fixups. Some test tweaking.

c272d41e2f Re-apply "SIL: Remove special meaning for @_semantics("stdlib_binary_only")" 
With -sil-serialize-all gone, this no longer means anything; just
don't declare the function as @_inlineable instead.

Fixes <rdar://problem/34564380>.

aab5f7aa4f Revert "SIL: Remove special meaning for @_semantics("stdlib_binary_only")" (#12270) 
It still affects StdlibUnittest, which is still using -sil-serialize-all.

53b8419279 [stdlib] Make all the stdlib APIs @_inlineable 
This change in theory should allow us to remove a special stdlib-only
sil-serialize-all compilation mode.

... and add a test to ensure that the next attempt at writing this
optimization won't introduce a regression.
