* Several TH/quasiquote changes
a) Added quasi-quote forms for
declarations
types
e.g. f :: [$qq| ... |]
b) Allow Template Haskell pattern quotes (but not splices)
e.g. f x = [p| Int -> $x |]
c) Improve pretty-printing for HsPat to remove superfluous
parens. (This isn't TH related really, but it affects
some of the same code.)
A consequence of (a) is that when gathering and grouping declarations
in RnSource.findSplice, we must expand quasiquotes as we do so.
Otherwise it's all fairly straightforward. I did a little bit of
refactoring in TcSplice.
User-manual changes still to come.
