342c3e6061 fox32+fox32rom: Remove the concept of "fast" and "shared" memory
Instead of having two banks of RAM, just have one bank. This requires
the use of some cursed code, but it's fine :P

fe279c4d85 fox32: Introduce better error handling
Instead of panicing, we now just print an error and exit in some

the panic handler instead though?

e8287097ad 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

fe476414b7 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.
