Implemented in this patch is also more jumps, loop instructions, and the
`out` instruction. With this patch, the 5150 BIOS can now checksum
itself.

This patch loads and runs the 5150 BIOS, and implements the instructions
necessary to pass the 8088 processor test done by the BIOS on boot.
The 5150 BIOS ROM is loaded with a TLB-like address lookup buffer that
is prefilled with entries that point to BIOS ROM in the host memory.
This TLB-like buffer will likely evolve to a full TLB in the far future
when we implement paging.
