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.

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 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.

Constraints. These concepts are already present in the current ValueState, but
the implementation is monolothic. Making ValueState more modular opens up new
design choices for customizing the analysis engine.

In the context of the analysis engine, the "Environment" is the binding between
Expr* (expressions) and intermediate symbolic values (RValues).

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.
