and start simplifying the interfaces in SourceManager that can fail.

llvm-svn: 98594

SourceManager's getBuffer() (and similar) operations. This abstract
can be used to force callers to cope with errors in getBuffer(), such
as missing files and changed files. Fix a bunch of callers to use the
new interface.

Add some very basic checks for file consistency (file size,
modification time) into ContentCache::getBuffer(), although these
checks don't help much until we've updated the main callers (e.g.,
SourceManager::getSpelling()).

on unqualified declarations.

Patch by Enea Zaffanella!  Minimal adjustments:  allocate the ExtInfo nodes
with the ASTContext and delete them during Destroy().  I audited a bunch of
Destroy methods at the same time, to ensure that the correct teardown was
being done.

injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template 
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.

Rename to addPPCallbacks since we're effectively adding a callback and maybe chaining it to an existing one

Don't assert if PP already contains a valid PP callback. The PP can handle multiple callbacks (using PPChainedCallbacks)
