bb92162dba Zero, not NULL. 
Not that there's a practical difference, but we should be clear that
we're zeroing out memory because its contents are vm_8bit values, not
pointers.

f44b029083 We need to check P's value as well 
This test broke once we began to (properly) push P onto the stack.
However, I'm not _clear_ on whether we should push P before or after we
set the INTERRUPT bit... We'll go with things as-is for now.

96b2542ea6 CARRY should be set if oper > 0 
This error became apparent once we added the missing modify_status
function to some instructions.

00ff9f069d Vastly simplify unit tests for mos6502 
Criterion's init and fini config options allow us to register setup and
teardown functions. We now use this to register the common cpu variable
for the mos6502 tests, albeit through the use of a global variable.

Doing so necessitated that each of the different test files have their
own suites, due to some implementation details in Criterion, but this is
No Big Deal.

50a84b4099 Remove cycles field from mos6502 struct 
It was both unused and not necessary, as we can simply compute the
number of cycles in the execute function.
