the use of some cursed code, but it's fine :P

fox32: Introduce better error handling

Instead of panicing, we now just print an error and exit in some
situations where a panic is too verbose. Maybe we should just change
the panic handler instead though?

fox32: Use the instruction size when reading from an immediate pointer
...
Previously, Operand::ImmediatePtr always read 32 bits from memory, then
truncated the value if the instruction size was smaller. Technically
this worked, but it would cause fox32 to print warnings if reading a
value at the very end of memory, because it would attempt to read past
the end of memory. Now, Operand::ImmediatePtr contains the instruction
size which is used by read_source().
This reverts commit 634a776a631c8e34f138dfbbfebf1c5cc74b6f05

fox32: Add 3 extra bytes at the end of fast and shared memory
...
Because Operand::ImmediatePtr always reads 4 bytes (even if the
instruction size is smaller), attempting to read the last byte of
memory through a pointer would cause fox32 to warn about reading
unmapped memory. Adding 3 extra bytes to the end of memory prevents
this.
