Split parser into parser itself, opcodes dumper and syntax errors checker.
...
Add internal hash map of literal indexes:
In this hash map key is pair of block number and literal's unique identifier in the block, and the value is a literal index that unique in the whole program.
Block is a continues array of opcodes. So, bytecode is splitted into blocks.
Each block has its own uid counter. To get literal index the interpreter looks up it in the hash map.
Thus, now JS program is able to have more than 255 identifiers/string literals.
The first 128 (0-127) uids are reserved for block's uid counter, the other 128 (128-255) are reserved for tmp variables.

Implementing resize of heap blocks.
...
- adding mem_heap_try_resize_block routine that tries to resize
block using free space that is located right after the resized block;
- placing long-term blocks from start of heap space and short-term - from end
of the space to increase probability of success of resizing just allocated
long-term block;
- adding mem_heap_try_resize_block invocation to 'test_heap' unit test.
