Two new entities were introduced - scopes and pre-parser. Two new entities were introduced - scopes and pre-parser.
* There are two types of scopes in the parser: global scope and function declaration scope. Notice that function expressions do not create a new scope in terms of the parser. A reason why is described below. * There are two types of scopes in the parser: global scope and function declaration scope. Notice that function expressions do not create a new scope in terms of the parser. A reason why is described below. Parsing process starts on global scope. If a function declaration occurs string the process, new scope is created, this new scope is pushed to a stack of current scopes; then steps 1-3 of parsing are performed. Note, that only global scope parsing shall merge all scopes into a byte-code. All scopes are stored in a tree to represent a hierarchy of them.

* Pre-parser. This step performs hoisting of variable declarations. First, it dumps `reg_var_decl` opcodes. Then it goes through the script and looks for variable declaration lists. For every found variable in the scope (not in a sub-scope or function expression) it dumps var_decl opcode. After this step byte-code in the scope starts with optional `'use strict'` marker, then `reg_var_decl` and several (optional) `var_decls`. * Pre-parser.

Due to some limitations of the parser, some parsing functions take `this_arg` and/or `prop` as parameters. They are further used to dump `prop_setter` opcode. Due to some limitations of the parser, some parsing functions take `this_arg` and/or `prop` as parameters. They are further used to dump `prop_setter` opcode. During parsing all necessary data is stored in either stacks or scope trees. After parsing of whole program, the parser merges all scopes into a single byte-code, hoisting function declarations in process. This task, so-called post-parser, is performed by `scopes_tree_raw_data` (jerry-core/js/scopes-tree.c) function. For further information about post-parser, check opcodes dumper section.
