ParseSectionSpecifier - Parse the section specifier indicated by "Spec". This is a string that can appear after a .section directive in a mach-o flavored .s file. If successful, this fills in the specified Out parameters and returns an empty string. When an invalid section specifier is present, this returns a string indicating the problem. If no TAA was parsed, TAA is not altered, and TAAWasSet becomes false.
