673e6c84d1 vm/tests: preserve order when decoding Map item.
When using Go's `map` for decoding, order can change from time to time,
while we may want to check it too. Use custom decoder for saving items
in order.

0cb6dc47e4 vm: implement slot-related opcodes
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.
