compiler: reverse args in AppCall
...
Invoked contract is expecting first argument to be on top of the stack.
Change test to use non-commutative operation to catch this behaviour.

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.

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

compiler: fix a bug with FromAddress handling
...
Conversion of string to address with FromAddress is performed
at compile time so there is no need to push parameters on stack.
