patch: make SVals.h conform to the naming guide

Hi Ted,

I uploaded a patch to Issue 4186056: Make SVals.h conform to the LLVM naming guide: methods should start with lowercase - Code Review (also
attached) to make the methods in SVals.h conform to the naming guide.
Would you please review it? Thanks,
