Fix the build.  Apparently MachineInstr& is no longer implicitly convertable to MachineBasicBlock::iterator.

rather than depending on LiveVariables.  This decreases compile time from:
0.5909s (LV + Regalloc) to 0.421s (just regalloc).

This one is x86-32-Darwin specific.

This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason.  I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

Do not CSE DEBUG_LOC, DBG_LABEL, DBG_STOPPOINT, DECLARE, and EH_LABEL SDNode's. This improves compile time slightly at -O0 -g.

soft float: experiments show that targets aren't
expecting this for results or for operands.  Add
support select/select_cc result soft float and
correct operand soft float for these.

into phis.  This is actually the same bug as PR2262 /
2008-04-29-VolatileLoadDontMerge.ll, but I missed checking the first 
predecessor for multiple successors.  Testcase here:

   of undef.
2) fix vector comparisons with undef to return a vector result instead

3) fix vector comparisons with evaluatable results to return vector
   true/false instead of i1 true/false (PR2529)
