ASCIIFastPath.h introduced in https://trac.webkit.org/changeset/104127 ,
but on ARM we get zillion warning from it:

/home/webkitbuildbot/oszi/WebKitNix/Source/WTF/wtf/text/ASCIIFastPath.h: In instantiation of 'bool WTF::charactersAreAllASCII(const CharacterType*, size_t) [with CharacterType = short unsigned int; size_t = unsigned int]':
/home/webkitbuildbot/oszi/WebKitNix/Source/WTF/wtf/text/WTFString.h:606:66:   required from here
/home/webkitbuildbot/oszi/WebKitNix/Source/WTF/wtf/text/ASCIIFastPath.h:88:9: warning: cast from 'const short unsigned int*' to 'const MachineWord* {aka const unsigned int*}' increases required alignment of target type [-Wcast-align]

This cast is safe, because the adress is aligned here. Patch is coming soon.
