LibX86: Add a way for Instruction::to_string() to symbolicate addresses
...
This patch adds a pure virtual X86::SymbolProvider that can be passed
to Instruction::to_string(). If the instruction contains what appears
to be a program address, stringification will try to symbolicate that
address via the SymbolProvider.
This makes it possible (and very flexible) to add symbolication to
clients of the disassembler. :^)

LibX86: Decode RDRAND instruction
...
I was looking at Kernel::get_good_random_bytes() and wondering where
the RDRAND instruction was. :^)

LibX86: Fix duplicate '+' in SIB byte disassembly
...
For SIB bytes with base but no index, we were emitting two '+' chars
which looked very off.

LibX86: Tolerate invalid segment register indices when disassembling
...
While #6 and #7 are not valid segment register, they can still be
encoded in otherwise-valid instructions, so let's tolerate it.

LibX86: Don't choke on invalid LOCK prefixes for now

This might be interesting information later, but I'm not sure how to
encode it at the moment.

for future tools like debuggers and such. :^)
