Rewrite chain handling validation and input TokenFactor handling
stuff now that we don't care about emulating the old broken
behavior of the old isel. This eliminates the
'CheckChainCompatible' check (along with IsChainCompatible) which
did an incorrect and inefficient scan *up* the chain nodes 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.
Removing the CheckChainCompatible nodes also shrinks the
generated tables by about 6K for X86 (down to 83K).
There are two pieces remaining before I can nuke PreprocessRMW:
1. I xfailed a test because we're now producing worse code in a
case that has nothing to do with the change: it turns out that
our use of MorphNodeTo will leave dead nodes in the graph
which (depending on how the graph is walked) end up causing
bogus uses of chains and blocking matches. This is really
bad for other reasons, so I'll fix this in a follow-up patch.
2. CheckFoldableChainNode needs to be improved to handle the TF.

Teach the grouper some simple tricks about looking contradictory
predicates. For example if we have:
Scope:
CheckType i32
ABC
CheckType f32
DEF
CheckType i32
GHI
Then we know that we can transform this into:
Scope:
CheckType i32
Scope
ABC
GHI
CheckType f32
DEF
This reorders the check for the 'GHI' predicate above
the check for the 'DEF' predidate. However it is safe to do this
in this situation because we know that a node cannot have both an
i32 and f32 type.
We're now doing more factoring that the old isel did.

of the matched pattern to use the newly created node results. Onto
the "making it actually work" phase!

Lots of improvements to the new dagisel emitter. This gets it to
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.

add support for referencing registers and immediates,
building the tree to represent them but not emitting
table entries for them yet.

rename the child field to 'next'. This is not a parent/child
relationship, this is a linear list relationship.

Emulate the current isel's "IsChainCompatible" logic for now.
I'd like to eventually rip it out, but for now producing the
same selections as the old matcher is more important.

convert the new matcher to check intermediate nodes for a single
use and only call IsProfitableToFold/IsLegalToFold on the load
being folded, like the old dagiselemitter does. This
substantially simplifies the code and improves opportunities for
sharing.

Check in the first big step of rewriting DAGISelEmitter to
produce a table based matcher instead of gobs of C++ Code.
Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).
The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp). When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.
There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.
