Source/WTF: 

When invoking StringImpl::startsWidth() or StringImpl::endsWith() with
a string literal, a new String was constructed implicitly, allocating
a new StringImpl and copying the characters for the operation.

This patch adds a version of those methods for single characters and
string literals.
This allows us to avoid allocating memory and use the characters in place,
and it permits some extra shortcuts in the implementation.
