Some instructions have a fixed Z register and don't have an explicit
register operand. This can be worked around by simply printing the
operand directly if the particular register class is detected.
The LPM and ELPM instructions also needed a custom decoder, which is
also included in this patch.

Not all operands are correctly disassembled at the moment. This means
that some machine instructions won't have all the necessary operands
set.
To avoid asserting, print an error instead until the necessary support
has been implemented.

printInst prints a branch/call instruction as `b offset` (there are many
variants on various targets) instead of `b address`.
It is a convention to use address instead of offset in most external
symbolizers/disassemblers. This difference makes `llvm-objdump -d`
output unsatisfactory.
Add `uint64_t Address` to printInst(), so that it can pass the argument to
printInstruction(). `raw_ostream &OS` is moved to the last to be
consistent with other print* methods.
The next step is to pass `Address` to printInstruction() (generated by
tablegen from the instruction set description). We can gradually migrate
targets to print addresses instead of offsets.
In any case, downstream projects which don't know `Address` can pass 0 as
the argument.

For some targets, there is a circular dependency between InstPrinter and
MCTargetDesc. Merging them together will fix this. For the other targets,
the merging is to maintain consistency so all targets will have the same
structure.
