walkstate -> walkstmt
walktype -> walkexpr; stmts moved to walkstmt

walktype and friends have a final Node **init
argument that can have side effects appended,
making it more explicit when they do and do not happen.
this replaces the old global addtop and addtotop.

delete switch map and interface conversion cases
(dropped from the language months ago).

so remove code from go.y.

show original types in badtype; don't remove pointers.
not sure why this was here but it confuses things
if the bad part involves two named pointer types
