Fix some issues in WalkChainUsers dealing with
CopyToReg/CopyFromReg/INLINEASM.  These are annoying because
they have the same opcode before an after isel.  Fix this by
setting their NodeID to -1 to indicate that they are selected,
just like what automatically happens when selecting things that
end up being machine nodes.

With that done, give IsLegalToFold a new flag that causes it to
ignore chains.  This lets the HandleMergeInputChains routine be
the one place that validates chains after a match is successful,
enabling the new hotness in chain processing.  This smarter
chain processing eliminates the need for "PreprocessRMW" in the
X86 and MSP430 backends and enables MSP to start matching it's
multiple mem operand instructions more aggressively.

I currently #if out the dead code in the X86 backend and MSP

Rewrite chain handling validation and input TokenFactor handling

'CheckChainCompatible' check (along with IsChainCompatible) which

happened as the pattern was being formed and does the validation
at the end in HandleMergeInputChains when it forms a structural
pattern.  This scans "down" the graph, which means that it is
quickly bounded by nodes already selected.  This also handles
token factors that get "trapped" in the dag.

generated tables by about 6K for X86 (down to 83K).

   which (depending on how the graph is walked) end up causing
   bogus uses of chains and blocking matches.  This is really
