2023-10-22	Store the result of OP_POP in the last register as a word	Aryadev Chavali
	Instead of making routines to handle data in the `ret` register, just store the result of POP into the last word register. This means we are no longer using vm_pop_* or POP_ROUTINES for the vm_execute script on OP_POP: instead we'll just use vm_mov_* which automatically pops the datum for us, while moving the datum to the last register.

2023-10-21	Implemented vm routines for OP_OR_*	Aryadev Chavali

2023-10-21	Implemented vm routines for OP_NOT_*	Aryadev Chavali

2023-10-21	Added vm_execute_all which executes an entire program	Aryadev Chavali
	Handles OP_HALT
2023-10-21	Switched from floats to halfword	Aryadev Chavali
	Registers are now just words, with pushing from and moving to registers with specified subtypes just pushing those types into the word registers. That means there are 8 word registers which can act as 16 half word registers, which themselves can act as 64 byte registers.
2023-10-16	Implemented vm_print_* routines	Aryadev Chavali
	Prints each aspect of the vm, and vm_print_all does it all.
2023-10-16	MOV now uses the stack, removed register member in inst_t	Aryadev Chavali
	Instead of taking an operand and a register, mov just uses the stack for the operand. Therefore, there's no need for a register member in inst_t. As a result, PUSH_*_REGISTER now uses the operand for the register.
2023-10-15	Moved vm_* code to its own file (runtime.(h\|c))	Aryadev Chavali
