Assembly instrumentation: handle more instructions

[ramosian-glider]

Originally reported on Google Code with ID 282

On X86, almost any instruction can have a memory argument. At the moment we instrument
only a minority of them.

We could use MCInstrInfo/MCRegisterInfo to guess instruction memory properties.

Attached (very hackish) patch almost passes ffmpeg.
- it passes TargetMachine through global var, just because
- mishandles movzbl and, in general, determines memory access size from the size of
the other argument. It's wrong for a lot of instructions.

I may work on it some more later.
