Fixes #3487.
Resolve type aliases as well as type references when code-generating a block pointer's function signature. A block declared as
typedef F (^Blk)now reaches the underlying function type instead of panicking on theFalias. The new fixture compares that form with a direct block declaration and checks that both produce the same typedBlock<(c_int,), ()>pointer.The resolver already detects alias cycles; this change uses that existing path.
