http://llvm.org/bugs/show_bug.cgi?id=7377 Updated format string highlighting and fixits to take advantage of the new CharSourceRange class. - Change HighlightRange to allow highlighting whitespace only in a CharSourceRange (for warnings about the ' ' (space) flag) - Change format specifier range helper function to allow for half-open ranges (+1 to end) - Enabled previously failing tests (FIXMEs/XFAILs removed) - Small fixes and additions to format string test cases M test/Sema/format-strings.c M test/Sema/format-strings-fixit.c M lib/Frontend/TextDiagnosticPrinter.cpp M lib/Sema/SemaChecking.cpp llvm-svn: 106480
