belliash d9db6bbc26 There is no need for global working buffer in VM.

belliash 67ce98d924 Look for executed OP_CALL.
The build was successful.
Details 
Each function contains a list of all instructions inside, thus we should consider only OP_CALL that has already been executed. As the list is browsed from bottom to top, no more checks are necessary. The first match is what we
are looking for.

belliash b6161b0e4b Fix VM ByteCode debugging.
The build was successful.
Details 
Only executed bytecode should be registered for debugging. In this way we do not register all emitted bytecode and save some memory. What is more, this change registers the bytecode in correct executing order including jumps.
Previously all bytecode generated by compiler has been saved what made the bytecode to be saved in compile, not execute order.

belliash 6d27069590 Add new file for every chunk.
The build was successful.
Details 
Every chunk should has its own file associated, even if it is [MEMORY]. Otherwise, some false information can be provided by interpreter to developer.

belliash 178f3820f6 Enable debugging.
The build was successful.
Details 
This commit introduces ne debug feature. The PH7 Engine limits the VM dump to the global scope. Since Aer Script is fully object-oriented language the dump option contains only information about last call of OP_DONE. This change,
forces the VM to store all instructions set in a global container when debugging is enabled, thus providing information the dump of whole script parse.

belliash 4dbd3ea412 New memory subsystem.
The build was successful.
Details 
This is a new memory subsystem implementing heap calculations as well as new builtin functions:
 * get_memory_usage()
 * get_memory_peak_usage()
 * get_memory_limit()
It also allows to set an upper memory limit, ensuring that processed script will not be able to allocate more memory from OS.
New subsystem is based on work done in 'memory_limit' branch. Big thanks to devnexen!
This finally fixes #25.

belliash b5fe36c14b There is no need for include_once() and require_once()
The build was successful.
Details 
Aer is object-oriented language and the code it includes is executed in the global scope. Global scope can contain only classes and namespaces and they cannot be re-declared. Thus every file can be included just once. We can
leave this to programmer, or take care about it on interpreter side. With this commit, include() and require() builtin functions allows to load file just once. Thanks to that, there is no need for include_once() and
require_once(). Done in scope of #30.

belliash af139b3f0a Reimplement C-like min() and max() functions.
The build was successful.
Details 
These functions should have C-like implementation and take exactly 2 arguments: integer or float.
Finally, C-implementation will be faster than using PH7 builtin library that needs to be compiled and interpreted.
