Daniel Dunbar 5618e98f33 Update tests to use %clang instead of 'clang', and forcibly disable use of '
clang ' or ' clang -cc1 ' or ' clang-cc ' in test lines (by substituting them to
garbage).

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Daniel Dunbar 7cea5f1747 Add a pretty horrible hack to prevent clang from crashing with inconsistent PCH
files.
 - The issue is that PCH uses a stat cache, which may reference files which have
   been deleted or moved. In such cases ContentCache::getBuffer was returning 0
   but most clients are incapable of dealing with this (i.e., they don't).

   For the time being, resolve this issue by just making up some invalid file
   contents and. Eventually we should detect that we are in an inconsistent
   situation and error out with a nice message that the PCH is out of date.

Argyrios Kyrtzidis 11a846ab53 Fixes for a couple of things:
- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function.
- C++ out-of-line method definitions didn't get an access specifier.

Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()).

Steve Naroff 7cae42b07a This patch includes a conceptually simple, but very intrusive/pervasive change.
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. 

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

Douglas Gregor 27821cee82 Make ASTContext explicitly keep track of the declaration for the C
FILE type, rather than using name lookup to find FILE within the
translation unit. Within precompiled headers, FILE is treated as yet
another "special type" (like __builtin_va_list).

This change should provide a performance improvement (not verified),
since the lookup into the translation unit declaration 
forces the (otherwise unneeded) construction of a large hash table.
More importantly, with precompiled headers, the construction
of that table requires deserializing most of the top-level
declarations from the precompiled header, which are then unused.

Fixes PR 4509.

Douglas Gregor 0086a5a3bb Introduce the notion of "Relocatable" precompiled headers, which are built
with a particular system root directory and can be used with a different
system root directory when the headers it depends on have been installed.
Relocatable precompiled headers rewrite the file names of the headers used
when generating the PCH file into the corresponding file names of the 
headers available when using the PCH file.

Addresses <rdar://problem/7001604>.

Douglas Gregor 1342e84c17 Fix PR 4489, a crash in PCH loading that occurs when loading the name
of a top-level declaration loads another top-level declaration of the
same name whose type depends on the first declaration having been
completed. This commit breaks the circular dependency by delaying
loads of top-level declarations triggered by loading a name until we
are no longer recursively loading types or declarations.

Douglas Gregor e6648fb79e Implement checking for macro definitions that occur on the command
line when using a PCH that were not provided when building the PCH
file. If those names were used as identifiers somewhere in the PCH
file, reject the PCH file.

Douglas Gregor c379c07240 Allow some differences between the predefines buffer used to build a
PCH file and the predefines buffer used when including the PCH
file. We (explicitly) detect conflicting macro definitions (rejecting
the PCH file) and about missing macro definitions (they'll be
automatically pulled from the PCH file anyway).

We're missing some checking to make sure that new macro definitions
won't have any impact on the PCH file itself (e.g., #define'ing an
identifier that the PCH file used).

Steve Naroff 3c301dc573 Sema::ActOnStartClassInterface(): Use PushOnScopeChains().
This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate.
