No way to access compile time switches/options in later compiler passes

[singul4ri7y]

Currently as the situation stands, we do not have any way to access compile time switches passed to the Pallene compiler in later compiler passes.

For example, if any custom switch is implemented and passed to the compiler such as:

pallenec --any-custom-switch module.pln

there is no way to know whether --any-custom-switch was used in compiler in later compiler passes like IR Generation or Code Generation.

This could stage as a good improvement.

Intermediate implementation has been done over it. Though it's not completely matured, the current implementation should do the trick.
