Now that the dust has settled on the Decl refactoring, I noticed FieldDecl didn't need NextDeclarator.  As a result, I'm removing it. 

Removing both slots (NextDeclarator/Next) end up reducing the size of fields/ivars by 40%.

causing SPASS to fail.

Move Decl::NextDeclarator (w/ setters/getters) down to ScopedDecl/FieldDecl.

Decl is now svelte:-)

Phase 2 of making the Decl class more lightweight...

Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.

Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.

a limited form of PHI nodes.  This finally fixes PR1639, speeding 179.art up
from 7.84s to 3.13s on PPC.

Add "ScopedDecl" AST, used by ValueDecl and TypeDecl. 

This allows us to sink the "Next" field, which isn't used by FieldDecl and ObjcIvarDecl.

1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.
