c30405e0ee Change ConstantPoolSDNode to actually hold the Constant itself instead of 
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.

33900811ee Fix some bugs in the alpha backend, some of which I introduced yesterday, 
and some that were preexisting.  All alpha regtests pass now.

371e49515d Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty 
fixme from the PowerPC backend.  Emit slightly better code for legalizing
select_cc.

53676dfd33 Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode. 
This is the last MVTSDNode.

This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.

Also, remove some uses of dyn_cast that should really be cast (which is
cheaper in a release build).

a7220851c0 Make several cleanups to Andrews varargs change: 
1. Pass Value*'s into lowering methods so that the proper pointers can be
   added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
   into any load/stores from the valist that are emitted

1ef3c0c798 Get rid of all symbolic loads. I now do gernate all relocations sequences 
rather than relying on the assembler.  Only a few more pseudo instructions
left.  Also merge load code paths.

a50adcf57d So, it turns out I forgot that one valid way of restoring GP after a call 
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.

should be able to handle this case.  The code is there, so let's see
