fd52dee79f compiler: process literals in analyzeVoidCalls
Function call can occur in the slice or map literal
and its result surely isn't unused.

b18a7f200c compiler: calculate local variables properly
In case when right-hand side of an assignment is a function,
left-hand side should be used.

This was probably a part of some earlier logic.

a781d299e0 compiler: use fully-qualified names for tracking functions
Function name now consists of 3 parts:
1) full package path
2) method receiver type (if any)
3) function name itself .

Fix #1150.

ed45ff98e3 compiler: process interop together with package
Closes #913.
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.

Related #941.

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.

75fb3af48f compiler: add basic support for function literals

Nested function literals and variables from closure are not supported for now.

a43c9b9246 compiler: calculate stack size more precisely
When calculating number of local variables, only
defining assignments (i.e. via `:=`) must be taken into account.

5e229d84d4 compiler: use uint16 for label numbers
As noted in #687 this will make compiler a bit more predictable.

852e6a335b 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.
