compiler: do not store constants as variables
...
Because the constants are loaded directly via `emitLoadConst`, there is no need to store
them in an array of locals. It can have a big overhead, because it
is done at the beginning of every function.

compiler: fix a bug with assignment to underscore
...
When using underscore it does not appear in the list
of local variables, so it can't be assigned.
In this commit the value is dropped.

compiler: optimize append argument processing
...
Append should leave it's result on top of the stack.
Thus we need to transform top of the stack:
(top) a . b --> (top) a . b . b
It can be done with just OVER + SWAP.

compiler: support panic
in source
...
In situations where VM's FAULT state needs to be reached,
panic function can be used. It compiles to THROW instruction.

compiler: emit integers correctly
...
A while ago VM serialization format for Integer items was changed
but compiler continued to emit Integers in old format.
This commit changes compiler behaviour to be compatible with VM.

compiler: move tests from vm/tests
...
These don't belong to VM as they compile some Go code and run it in a VM. One
may call them integration tests, but I prefer to attribute them to
compiler. Moving these tests into pkg/compiler also allows to properly count
the compiler coverage they add:
-ok github.com/CityOfZion/neo-go/pkg/compiler (cached) coverage: 69.7% of statements
+ok github.com/CityOfZion/neo-go/pkg/compiler (cached) coverage: 84.2% of statements
This change also fixes `contant` typo and removes fake packages exposed to the
public by moving foo/bar/foobar into the testdata directory.
