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
