Reviewed by Darin Adler.

I only modified the default build for OSX and Chromium's build file to include WTFCompileAsserts.cpp
as those should be sufficient to catch regressions on the size of the data structures.

• JavaScriptCore.gypi: Added the WTFCompileAsserts.cpp file.
• JavaScriptCore.xcodeproj/project.pbxproj: Added the WTFCompileAsserts.cpp file.
• runtime/UString.cpp: Added a compile assert for UString size.
• wtf/SizeLimits.cpp: Added compile asserts for data structures that didn't have cpp files.
• wtf/text/StringImpl.cpp: Added a compile assert for StringImpl size.
