-Renamed ContextDecl -> DeclContext
-Removed DeclContext pointer from FieldDecl
-EnumDecl inherits from DeclContext, instead of TagDecl

Patch by Argiris Kirtzidis!

llvm-svn: 49261

-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

better name is welcome :)

First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

allocation through ASTContext.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

Right now only some ctors are switched over.  I need to switch them all
over so I can change the dtor over.

This lets us experiment with region allocation and other things in the 
future.

rename QualType::getQualifiers to getCVRQualifiers.
Add some fixme's and clean up some code relevant to qualifiers.
Change ASQualType to contain a Type* instead of a QualType.  
Any CVR qualifiers should be on the outer qual type.

IncompleteArrayType.  This should make code dealing with both incomplete 
and variable length arrays much more readable, plus it allows properly 
making the distinction between isVariableArrayType() and 
isVariablyModifiedType().  The patch is a little big, but it's 
strightforward. so I don't think there should be any issues.

Tighten up ASTContext::typesAreCompatible()...it needs to make sure the qualifiers match. The comment and C99 citation for this routine were correct...the code needed to conform to the comment/spec. This fixes the test added below.

Tightening up this routine forced tweaks to Sema::CheckSubtractionOperands() and Sema::CheckCompareOperands(). For example, they both need to operate on the unqualified pointee...

Fix bz1950. ASTContext::functionTypesAreCompatible() needs to operate on the unqualified parameter types (per C99 6.7.5.3p15).

Add a FIXME to commit r45784. Thanks mrs!

Fix ASTContext::typesAreCompatible to allow for int/enum compatibility (C99 6.7.2.2p4).
Fix Sema::MergeFunctionDecl to allow for function type compatibility (by using the predicate on ASTContext). Function types don't have to be identical to be compatible...
