Douglas Gregor 4feb36de04 Remove DeclGroupOwningRef, since we intend for declarations to be owned 
by DeclContexts (always) rather than by statements. 

DeclContext currently goes out of its way to avoid destroying any
Decls that might be owned by a DeclGroupOwningRef. However, in an
error-recovery situation, a failure in a declaration statement can
cause all of the decls in a DeclGroupOwningRef to be destroyed after
they've already be added into the DeclContext. Hence, DeclContext is
left with already-destroyed declarations, and bad things happen. This
problem was causing failures that showed up as assertions on x86 Linux
in test/Parser/objc-forcollection-neg-2.m.

Steve Naroff 13ae6f47cd Remove many references to ASTContext::getAllocator(), replacing them with calls to the recently added placement new (which uses ASTContext's allocator for memory). Also added ASTContext::Deallocate(). 
This will simplify runtime replacement of ASTContext's allocator. Keeping the allocator private (and removing getAllocator() entirely) is also goodness.

Ted Kremenek 6d60a4ec19 Modified DeclGroupRef to always load/store the internal pointer value as Decl*. This hopefully will obviate any concerns with violating strict type-aliasing issues.

Ted Kremenek 6ed79f0c13 Use a union instead of a bunch of magic casts to implement a variant. This removes the type-punning errors for DeclGroup.

Ted Kremenek a5e23f6b78 Added prototype implementation of the DeclGroup, DeclGroupRef, and DeclGroupOwningRef classes. 
Documentation and testing are pending.
