MERGE TO STABLE

Fix two small Template Haskell bugs.

(1) A bug in the renaming of [d| brackets |].  The problem was
that when we renamed the bracket we messed up the name cache, because
the module was still that of the parent module.  Now we set a fake
module before renaming it.

TH_spliceDecl4 is the test.

(2) An expression splice can in principle mention *any* variable,
so the renamer really has to assume that it does when doing depdendency
analysis.  For example
	f = ...
	h = ...$(thing "f")...
The renamer had better not put 'h' before 'f', else the type checker
won't find a defn for 'f' in the type envt.

TH_spliceE5 is the test
