c6a4d1131e Make sure string benchmarks actually measure string operations 
The optimizer was sometimes able to eliminate most/all of the actual operations, so some benchmarks were not really measuring anything.

[benchmark] Eliminate usages of String.characters and CharacterView
 2017-10-06 17:05:14 -07:00
Max Moiseev
53ec0b1168 Improve StringEdits performance in absence of CharacterView 
CharacterView was not Hashable, so Set could not be used as an
accumulator. String and Substring are Hashable, but using a Set as an
accumulator is still slower than first collecting all the results in an
Array and then transforming it to a Set at the end. One possible reason
why that could be the case, is that by the time conversion happens, we
already know the capacity and thus will not re-allocate and re-hash a
Set on every insertion beyong current capacity.

bc235afcf8 [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]`

e15ea5fcf3 [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).

bd5189c25a [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.

2c0b69d241 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.
