This will be used to replace things like X86's MOV32to32_.

Enhance ScheduleDAGSDNodesEmit to be more flexible and robust
in the presense of subregister superclasses and subclasses. It
can now cope with the definition of a virtual register being in
a subclass of a use.

Re-introduce the code for recording register superreg classes and
subreg classes. This is needed because when subreg extracts and
inserts get coalesced away, the virtual registers are left in
the correct subclass.

in subset/superset relations. This function is used by the
fast-isel emitter, which always wants the super-most set.

Convert TargetRegisterInfo's super-register checking to use a pre-computed hash table just like subregister checking does.

in multiple register classes. Now, MVT::Other is only returned if the types
for those register classes differ.

 - Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

/Users/sabre/llvm/Debug/bin/tblgen: error:

instead of just:

This is all I plan to do with this, but it should be easy enough to improve if anyone 
cares (e.g. keeping more loc info in "dag" expr records in tblgen.
