Take advantage of the recent improvements to the liveintervals set (tracking

instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:
1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
better solution.
3. Implements PR865, "coallescing" away the second copy in code like:
A = B

B = A

Start eliminating temporary vectors used to create DAG nodes. Instead, pass
...
in the start of an array and a count of operands where applicable. In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap. In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.
I updated a lot of code calling getNode that takes a vector, but ran out of
time. The rest of the code should be updated, and these methods should be
removed.
We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.
It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

Revamp the "CSEMap" datastructure used in the SelectionDAG class. This
...
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a
home-grown hashtable.
This is still a work in progress: not all the maps have been moved over and the
hashtable never resizes. That said, this still speeds up llc 20% on kimwitu++
with -fast -regalloc=local using a release build.

thing. Doubles still need to be special cased.

Instructions with variable operands (variable_ops) can have a number required
...
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
"call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.
Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

Fix a nasty dag combiner bug that caused nondeterminstic crashes (MY FAVORITE!):
...
SimplifySelectOps would eliminate a Select, delete it, then return true.
The clients would see that it did something and return null.
The top level would see a null return, and decide that nothing happened,
proceeding to process the node in other ways: boom.
The fix is simple: clients of SimplifySelectOps should return the select
node itself.
In order to catch really obnoxious boogs like this in the future, add an
assert that nodes are not deleted. We do this by checking for a sentry node
type that the SDNode dtor sets when a node is destroyed.
