this massive patch introduces a simple new abstraction: it makes
"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.

This is an important distinction from the "FileID" currently tracked by
SourceLocation.  *That* FileID may refer to the start of a file or to a
chunk within it.  The new FileID *only* refers to the file (and its
#include stack and eventually #line data), it cannot refer to a chunk.

FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

add support for usage of cast to union thing with static vars

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62387 91177308-0d34-0410-b5e6-96231b3b80d8

Teach DeclContext how to find the primary declaration for any TagDecl
even when we are still defining the TagDecl. This is required so that
qualified name lookup of a class name within its definition works (see
the new bits in test/SemaCXX/qualified-id-lookup.cpp).

As part of this, move the nested redefinition checking code into
ActOnTag. This gives us diagnostics earlier (when we try to perform
the nested redefinition, rather than when we try to complete the 2nd
definition) and removes some code duplication.

Convert some more statement actions to smart pointers.
Fix a type error; parser wanted to pass the third part of a for-statement as a statement; should be expression.

ccc: Clean up (user level) error handling.
 - ccc now checks for existence of input files (more annoying to test,
   but matches gcc).
 - Fix some test cases.

eliminate FullSourceLoc::getLocation() now that FullSourceLoc
*is* the location.  This eliminates some weird X.getLocation().getLocation()'s.

Make FullSourceLoc derive from SourceLocation instead of
containing one.  Containment is generally better than derivation,
but in this case FullSourceLoc really 'isa' SourceLocation.

ccc: Darwin/X86: Implement remainder of (non -Z...) generic argument
translation.
 - As is my general strategy, this is initially pedantically
   compatible with gcc and can be cleaned up later. So, for example,
   we still pass -static to collect2 4 times if you say '-mkernel
   -fapple-kext'. ;)

As a performance optimization, don't bother calling MacroInfo::isIdenticalTo
if warnings in system headers are disabled.  isIdenticalTo can end up
calling the expensive getSpelling method, and other bad stuff and is
completely unneeded if the warning will be discarded anyway. rdar://6502956
