Reviewed by Alexey Proskuryakov.
These changes make the micro-benchmark of setting the text of a textarea about
4x faster.
* Source/WTF/wtf/text/StringView.cpp:
(WTF::makeStringBySimplifyingNewLinesSlowCase): Added. Implements a faster
algorithm for
standardizing line endings as opposed to making two passes through the string.
* Source/WTF/wtf/text/StringView.h:
(WTF::makeStringBySimplifyingNewLines): Added a high-speed check for '\r'
characters before doing
the slower algorithm to standardize line separators. Most strings won't have
any at all, and none
of the ones in the benchmark do.
