[stdlib] Update reduce benchmark to compare the two forms
...
The ReduceInto benchmark performs three tasks using both `reduce(_:_)` and `reduce(into:_:)` so that their performance can be compared:
1. Summing an array, reducing to `Int`
2. Filtering an array, reducing to `[Int]`
3. Counting letter frequencies, reducing to `[Character: Int]`

[stdlib] Implement reduce with inout (SE-0171)
...
Implement and document `reduce(into:_:)`, with a few notes:
- The `initial` parameter was renamed `initialResult` to match the first parameter in `reduce(_:_:)`.
- The unnamed `combining` parameter was renamed `updateAccumulatingResult` to try and resemble the naming of the closure parameter in `reduce(_:_:)`.
- The closure throws and `reduce(into:_)` re-throws.
- This documentation mentions that `reduce(into:_)` is preferred over `reduce(_:_:)` when the result is a copy-on-write type and an example where the result is a dictionary.
Add benchmarks for reduce with accumulation into a scalar, an array, and a dictionary.
Update expected error message in closures test (since there are now two `reduce` methods, the diagnostic is different).

[String] Grapheme fast paths for punctuation: 5-8x speedup.
...
Many strings use non-sub-300 punctuation characters (e.g. unicode
hyphen, CJK quotes, etc). This can cause switching between fast and
slow paths for grapheme breaking. Add in fast-paths for general
punctuation characters and CJK punctuation and symbol characters.
This results in about a 5-8x speedup for heavily (unicode) punctuated
Latiny and CJKy workloads.

benchmarks: Make sure there is no constant propagation in the StringBuilder benchmarks.
...
This fixes the StringAdder benchmark, where the string addition was completely constant folded.
It has only minimal effect on the other benchmarks in this file, because the optimizer didn't constant fold the strings there anyway.

CheckResults with auto-generated error message
...
In order to minimize impact of results checking on test performance, this removes the @autoclosure for error message.
Added new version of `CheckResults` that takes only `resultsMatch: Bool` - rest of the parameters are defaulted to `StaticString`s for method and file name, plus line number. Old method was deprecated, but left in place as tool for debugging failing checks. All tests were move to use the new method.
