Argyrios Kyrtzidis 9b36c3f0de 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.

Chris Lattner 6133aeb97d fix PR7360: -P mode turns off line markers, but not blank space. 
Apparently some programs which abuse the preprocessor depend 
on this.

Chris Lattner e127a0d801 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 8ed4ff6d05 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.
