strings.

[string] ASCII/UTF-8 fast paths for String.init(decoding:as:)
fd1c861 
Add some fast paths to String.init(decoding:as:) for inputs of
contiguously stored UTF-8 code units. Dramatically speeds up creation
when the String happens to be ASCII and we can form more small
strings.
@milseman milseman force-pushed the contiguous_stringage branch from 9866705 to fd1c861 Compare June 15, 2018 21:43
@milseman milseman changed the title [DO NOT MERGE] WIP: experiment with contiguously-stored protocol for use in String.i… [string] ASCII/UTF-8 fast paths for String.init(decoding:as:) Jun 15, 2018
