on the C64, if not using floats, disable basic ROM in startup to gain another 8Kb of RAM

MEMTOP is adjusted to $d000. This gives us 50 Kb of contiguous program RAM space. ($0801-$CFFF)

defers are now only registered/called when flow of control actually reached the defer statement
...
a defer statement sets its corresponding bit in a bitmask that is shifted in the defer handler routine to see what defer blocks to call.

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.
