828e080f3b Redo LegalizeTypes soft float support for
SINT_TO_FP and UINT_TO_FP.  This now produces
the same code as LegalizeDAG (the previous
code was based on a mistaken idea of what
LegalizeDAG did in this case).

b650adae49 Add a little wrapper header that is put around bc files when emitting
bc files for modules with a target triple that indicates they are for
darwin.  The reader unconditionally handles this, and the writer could
turn this on for more targets if we care.

This change has two benefits for darwin:

1) it allows us to encode the cpu type of the file in an easy to read
   place that doesn't require decoding the bc file.
2) it works around a bug (IMO) in darwin's AR where it is incapable of
   handling files that are not a multiple of 8 bytes long.  BC files
   are only guaranteed to be multiples of 4 bytes long.

caf8cb40e8 Make the local register allocator compute (purely local) liveness information for itself
rather than depending on LiveVariables.  This decreases compile time from:
0.5909s (LV + Regalloc) to 0.421s (just regalloc).

d609d7166c Make debug info come out in data-only files.
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.

9255845ac7 Remove custom expansion from LegalizeTypes when doing

expecting this for results or for operands.  Add

correct operand soft float for these.

c144216d78 Fix PR2496, a really nasty bug which involved sinking volatile loads
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:
