Certain x86 instructions use bits 3:5 of the byte following the opcode as an
opcode extension, with the decode sometimes depending on bits 6:7 as well.
Add support for this in the main decoding table rather than an ad-hock
adaptation per opcode.

This paves the way for multiple architecture support. Note that while
ioapic.c could potentially be shared with ia64, it is also moved.
