This patch only handles targets with one opcode specified so far, but

result nodes correctly.  Note that this includes a horrible hack
in DAGISelHeader which cannot be fixed reasonably without 
eliminating (parallel) from input patterns.  That, in turn,
can't be done until we support writing multiple result patterns
for the X86and_flag and related multiple-result nodes.

the point where it is to the 95% feature complete mark, it just
needs result updating to be done (then testing, optimization 
etc).

More specificallly, this adds support for chain and flag handling
on the result nodes, support for sdnodexforms, support for variadic
nodes, memrefs, pinned physreg inputs, and probably lots of other
stuff.

In the old DAGISelEmitter, this deletes the dead code related to
OperatorMap, cleans up a variety of dead stuff handling "implicit
remapping" from things like globaladdr -> targetglobaladdr (which
is no longer used because globaladdr always needs to be legalized),
and some minor formatting fixes.
