  - In an unqualified call g(x), even if the name does not refer to
    anything in the current scope, we can still find functions named
    "g" based on ADL. We don't yet have this ability.

Steve set me straight on this one. GCC was right, EDG was wrong: the
direct-initialization following a user-defined conversion can select
any constructor; it just can't employ any user-defined
conversions. So we ban those conversions and classify the constructor
call based on the relationship between the "from" and "to" types in
the conversion.

ABI handling API changes.
 - Lift CGFunctionInfo creation up to callers of EmitCall.

 - Move isVariadic bit out of CGFunctionInfo, take as argument to
   GetFunctionType instead.

No functionality change.

Split specific_decl_iterator, which had a run-time field for
determining what decls are acceptable, into specific_decl_iterator
(in which all decls matching the SpecificDecl type requirements are
acceptable) and filtered_decl_iterator (which also does a run-time
check via a member pointer non-type template parameter). This saves
some space in the iterators.

RewriteObjC::RewriteBlockDeclRefExpr(): Add parens to enforce precedence. This fixes <rdar://problem/6529468> clang ObjC rewriter: Need parenthesis around dereferences in rewritten Blocks.
