compiler: support implicit type in function arguments
...
Go supports declaring multiple arguments of the same type without
duplicating type name. Now we support this too.

compiler: support using return

When `return` is used in one codepath, but not the other,
we do not clean altstack properly. This commit fixes it.

compiler: add ability to generate .abi.json file
...
A part of integration with NEO Blockchain Toolkit (see #902 ). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
- hash of the compiled contract
- smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
- smart-contract entry point
- functions
- events
However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66 ).

compiler: fix bug with missing methods parameters
...
Method `methodInfoFromScope(...)` always returned an empty parameters
set, so we were missing this information in both .abi.json and
.debug.json files. Fixed now.

Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend

`a := x == 1 && y == 2`.
This commit makes all jumps in such conditions local
and adds tests.
