Simplify logic for avoiding concatenation after numeric constants.
...
I threw in a couple of test cases for UD-suffixes -- already working, but
it wasn't immediately obvious to me.

[Preprocessor] When checking if we can concatenate two tokens, check
...
if they were already concatenated in source using the spelling locations
even if they came from a macro expansion.
This fixes an issue where a GUID passed as macro argument ends up
malformed after preprocessing because we added spaces inside it.

User-defined literals: reject string and character UDLs in all places where the
...
grammar requires a string-literal and not a user-defined-string-literal. The
two constructs are still represented by the same TokenKind, in order to prevent
a combinatorial explosion of different kinds of token. A flag on Token tracks
whether a ud-suffix is present, in order to prevent clients from needing to look
at the token's spelling.
