* Add a HsExplicitFlag to SpliceDecl, to improve Trac #4042
The issue here is that
g :: A -> A
f
data A = A
is treated as if you'd written $(f); that is the call of
f is a top-level Template Haskell splice. This patch
makes sure that we *first* check the -XTemplateHaskellFlag
and bleat about a parse error if it's off. Othewise we
get strange seeing "A is out of scope" errors.
