- Change "ExternalSymbolSDNode" to "SymbolSDNode".

- Add linkage to SymbolSDNode (default to external).

Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* and
...
ConstantFP* instead of APInt and APFloat directly.
This reduces the amount of time to create ConstantSDNode
and ConstantFPSDNode nodes when ConstantInt* and ConstantFP*
respectively are already available, as is the case in
SelectionDAGBuild.cpp. Also, it reduces the amount of time
to legalize constants into constant pools, and the amount of
time to add ConstantFP operands to MachineInstrs, due to
eliminating ConstantInt::get and ConstantFP::get calls.
It increases the amount of work needed to create new constants
in cases where the client doesn't already have a ConstantInt*
or ConstantFP*, such as legalize expanding 64-bit integer constants
to 32-bit constants. And it adds a layer of indirection for the
accessor methods. But these appear to be outweight by the benefits
in most cases.
It will also make it easier to make ConstantSDNode and
ConstantFPNode more consistent with ConstantInt and ConstantFP.

lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted
...
by its first field, but TableGen doesn't actually enforce creating it that
way. TableGen sorts the records that will be used to create it by the names
of the records, not the Name field of those records.
This patch corrects the sort to use the "Name" field of the record as the
sort key.

Move the point at which FastISel taps into the SelectionDAGISel
...
process up to a higher level. This allows FastISel to leverage
more of SelectionDAGISel's infastructure, such as updating Machine
PHI nodes.
Also, implement transitioning from SDISel back to FastISel in
the middle of a block, so it's now possible to go back and
forth. This allows FastISel to hand individual CallInsts and other
complicated things off to SDISel to handle, while handling the rest
of the block itself.
To help support this, reorganize the SelectionDAG class so that it
is allocated once and reused throughout a function, instead of
being completely reallocated for each block.
