IR codegen: global vars with numeric initialization value are now also put into the VARIABLESWITHINIT section rather than requiring explicit code instructions to initialize them in INITGLOBALS.
...
Note that something similar, such as putting those variables inline in the program initialized with their value and all, cannot be done for the 6502 codegen: the program needs a mechanism to reset ALL variables when it runs a second time.
