Err on the side of brevity and rename (while providing aliases for the original name) -Wbool-conversions, -Wint-conversions, and -Wvector-conversions for consistency with constant, literal, string, and sign conversion warnings. And name the diagnostic groups explicitly while I'm here rather than rewriting the string in the groups and sema td files. Curiously, vector-conversion is not under -Wconversion. Perhaps it should be. llvm-svn: 152776
