e880e4c2d2 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. :^)

34d07e35bd LibX86: Decode RDRAND instruction
I was looking at Kernel::get_good_random_bytes() and wondering where
the RDRAND instruction was. :^)

8daddcfa0a LibX86: Fix duplicate '+' in SIB byte disassembly
For SIB bytes with base but no index, we were emitting two '+' chars
which looked very off.

1924112d7d 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.

16455e91db 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.

This will be very useful for developer tools like ProfileView, and also
for future tools like debuggers and such. :^)
