Daniel Dunbar 27734fdbbf Frontend: Factor out header include dumping (-H) into its own preprocessor
callbacks class.
 - Aside from being generally cleaner, this also allows -H to work correctly in
   modes other than standard preprocessing (e.g., -c, -MM, etc.)

Craig Silverstein 1a9ca21881 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.

Douglas Gregor 453b012513 Make sure to always check the result of
SourceManager::getPresumedLoc(), so that we don't try to make use of
an invalid presumed location. Doing so can cause crashes.

Chris Lattner 49609d56d7 make sure #pragma clang is treated the same way as #pragma gcc in -E mode,
unknown pragmas should just be passed through to the .i file.

Douglas Gregor c7d6576d54 When we parse a pragma, keep track of how that pragma was originally
spelled (#pragma, _Pragma, __pragma). In -E mode, use that information
to add appropriate newlines when translating _Pragma and __pragma into
#pragma, like GCC does. Fixes <rdar://problem/8412013>.

Daniel Dunbar d435275c59 Frontend: Add basic -H support.
- I didn't implement the GCC "multiple include guard" detection parts, because
   it doesn't seem useful or obvious.

Argyrios Kyrtzidis 36745fda34 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.

Apparently some programs which abuse the preprocessor depend

Chris Lattner fb24a3a4ec push some source location information down through the compiler,
into ContentCache::getBuffer.  This allows it to produce 
diagnostics on the broken #include line instead of without a 
location.

Dan Gohman 6e8427e066 Remove this hard-coded buffer size. In some basic experiments preprocessing
large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.

This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.
