Add HsSyn prettyprinter tests
Summary:
Add prettyprinter tests, which take a file, parse it, pretty print it,
re-parse the pretty printed version and then compare the original and
new ASTs (ignoring locations)
Updates haddock submodule to match the AST changes.
There are three issues outstanding
1. Extra parens around a context are not reproduced. This will require an
AST change and will be done in a separate patch.
2. Currently if an `HsTickPragma` is found, this is not pretty-printed,
to prevent noise in the output.
I am not sure what the desired behaviour in this case is, so have left
it as before. Test Ppr047 is marked as expected fail for this.
3. Apart from in a context, the ParsedSource AST keeps all the parens from
the original source. Something is happening in the renamer to remove the
parens around visible type application, causing T12530 to fail, as the
dumped splice decl is after the renamer.
This needs to be fixed by keeping the parens, but I do not know where they
are being removed. I have amended the test to pass, by removing the parens
in the expected output.
