Normalize wasm types (#1378)

Browse Source 
Normalize wasm types, for the two wasm types, if their parameter types
and result types are the same, we only save one copy, so as to reduce
the footprint and simplify the type comparison in opcode CALL_INDIRECT.

And fix issue in interpreter globals_instantiate, and remove used codes.
