We can now have up to 128 globals. The number is arbitrary, but could
go up to 256, since we have a byte to encode them. For now, their
number is statically determined, which can cause wasted space if not
all are used. We'll change this to be dynamic, the number of globals
will be encoded in the beginning of the bytecode, as is the case with
constants and globals will simply occupy the beginning of ordinary ram.
