and start simplifying the interfaces in SourceManager that can fail.

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()).

Also change this method to lookup property declarations using DeclContext::lookup().

a property has the same name as the ivar it wraps then the old logic
wouldn't find the previous property declaration.

comparing DeclContext pointers, to avoid having to remember to call
getPrimaryContext() everywhere. This is the last part PR6594.

llvm-svn: 98546

parameter hides a namespace-scope declararion with the same name in an
out-of-line definition of a template. The lookup requires a strange
interleaving of lexical and semantic scopes (go C++), which I have not
yet handled in the typo correction/code completion path.

Fixes PR6594.

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.

iterations of this patch gave explicit template instantiation
link-once ODR linkage, which permitted the back end to eliminate
unused symbols. Weak ODR linkage still requires the symbols to be
generated.

Fixes an assertion arising C overload analysis, but really I can't imagine
that this wouldn't cause a thousand other uncaught failures.
