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.

compiler: calculate stack size more precisely
...
When calculating number of local variables, only
defining assignments (i.e. via `:=`) must be taken into account.

compiler: move it up from vm
...
It really deserves it, I think. Especially given that it doesn't have any
direct usage of `vm` package now.
