This commit contains: -) adding the new instructions + infrastructure, like parsing, printing, etc. -) support in IRGen to generate global object-variables (i.e. "heap" objects) which are statically initialized in the data section. -) IRGen for global_value which lazily initializes the object header and returns a reference to the object. For details see the documentation of the new instructions in SIL.rst.
