Ruben Ayrapetyan 1fe2817457 Introduce parser-time optimization that moves function's argument values to registers. 
For functions with the optimization applied:
 - vm puts arguments values immediately to registers without putting them to variables in lexical environment;
 - number of arguments is extracted from corresponding 'reg_var_decl' instruction's argument;
 - for functions that also don't have local variables, lexical environments are not created.

Ruben Ayrapetyan 31894da098 Move ecma-stack to vm component, renaming it to vm-stack. 
ECMA-stack is related to VM and is not related to ECMA component, except for GC.
Dependency between vm-stack and GC would be solved after GC would be extracted to a separate compoment.
