Added support for indirect-gotos (GCC extension) in source-level CFGs.
This involves the construction of a specialized "dispatch" block that
all basic blocks containing indirect gotos unconditionally transfer
control-flow to. The successors of the dispatch block has as its successors
all of the blocks containing labels whose address was taken somewhere in
the function.

Implement more thoughful error recovery when dealing with bogus declarator types.
For example, the following code was resulting in spurious warnings. This was the result of
Sema::GetTypeForDeclarator() synthesizing a type to hand back to the caller (in this case,
"int []", instead of "struct s[]", which is invalid).
struct s;
struct s* t (struct s z[]) { // expected-error {{array has incomplete element type}}
return z;
}
Strategy: Flag the error in Declarator/DeclaratorChunk. This info is later stored in
the ParmVarDecl. If the decl is referenced, Sema::ParseIdentifierExpr() will check if
the type is invalid. If so, it quietly returns "true", without instantiating a DeclRefExpr.
This seems to work nicely. If Chris is happy with the approach, I will generalize this to
all VarDecls.

Changes to CFGBuilder:
+ Added the creation of an empty Entry block at the end of CFG
construction if the Entry block in the CFG contains multiple
predecessors (which can happen with labels and do loops).
+ Fixed bug in the creation of an empty Exit block with functions where not
all paths end in a return statement (but some do). Basic blocks with
return statements were jumping to a (sometimes) non-empty block.
+ FinishBlock no longer checks for labels at the beginning of a basic
block before reversing the statements in the block. This is because
the recursion invariants of the builder methods have been cleaned up,
and blocks are only passed to FinishBlock at most once.
+ Modified handling of "if", "for", "while", "do", and "switch" to allow
condition expressions that can span multiple basic blocks. This allows
such conditions to contain short-circuit expressions (which span multiple
blocks in the CFG).
