Workaround for x86 optimizer bug in MSVC 2012.
https://bugs.webkit.org/show_bug.cgi?id=118478
Reviewed by Benjamin Poulain.
This is a workaround for a bug in the x86 MSVC 2012 optimizer.
The problem is that the range comparison gets optimized out when
the templated inline function toASCIIUpper. Copying the methods
content fixes the problem.
This is unfortunately not the nicest fix, but the alternative would
be to turn off optimization for StringImpl::upper on the x86 MSVC 2012
build, which might impact overall performance negatively.
