Doug Gregor pointed out some problems with debug mode enabled in one TU and not another.  This patch helps detect those situations and offers improved error messages to help get debug mode enabled in more TU's when it is absolutely necessary to do so.  Thanks Doug.

[analyzer] Refactor: make PathDiagnosticLocation responsible for validation of SourceLocations (commit 5 of ?):
 - Get rid of PathDiagnosticLocation(SourceRange r,..) constructor by providing a bunch of create methods.
 - The PathDiagnosticLocation(SourceLocation L,..), which is used by crate methods, will eventually become private.
 - Test difference is in the case when the report starts at the beginning of the function. We used to represent that point as a range of the very first token in the first statement. Now, it's just a single location representing the first character of the first statement.
