Rename tok::eom to tok::eod.
...
The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

Frontend: Factor out header include dumping (-H) into its own preprocessor

modes other than standard preprocessing (e.g., -c, -MM, etc.)

Several PPCallbacks take an SourceLocation + IdentifierInfo, rather
...
than a Token that holds the same information all in one easy-to-use
package. There's no technical reason to prefer the former -- the
information comes from a Token originally -- and it's clumsier to use,
so I've changed the code to use tokens everywhere.

Modify the pragma handlers to accept and use StringRefs instead of IdentifierInfos.
...
When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded).
We can avoid this if we just use StringRefs for the pragmas.
As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified.

Remove this hard-coded buffer size. In some basic experiments preprocessing

large files, this doesn't seem significantly better than just letting

raw_ostream.
