c81f0af6b7 Testcase for pr6552. I changed the code to use "ip" instead of "fp" because
the "fp" register name is not valid on Darwin, and the "ip" register name was
broken for all ARM targets.

ebc64cf780 Lower add (mul a, b), c into MACCU / MACCS nodes which translate
directly to the maccu / maccs instructions. We handle this in
ExpandADDSUB since after type legalisation it is messy to
recognise these operations.

f7b730425f The address of an indirect call must be in R12 on Darwin.
Make it so.  (This patch is in LowerCall_Darwin, which seems
to be used by SVR4 code as well; since that doesn't belong here,
I haven't worried about this case.)

57578766aa simplify EmitSectionOffset to always use .set if it is

.set in one case we didn't before, which shouldn't harm

instead of duplicating it.

f5fd499791 Fix a crash compiling 254.gap for Thumb2. The Thumb2 add/sub with 12-bit
immediate instructions cannot set the condition codes, so they do not have
the extra cc_out operand.  We hit an assertion during tail duplication
because the instruction being duplicated had more operands that expected.

314fef6127 Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This

53e000bac3 Better handling of dead super registers in LiveVariables. We used to do this:
CALL ... %RAX<imp-def>
   ... [not using %RAX]
   %EAX = ..., %RAX<imp-use, kill>
   RET %EAX<imp-use,kill>

Now we do this:

   CALL ... %RAX<imp-def, dead>
   ... [not using %RAX]
   %EAX = ...
   RET %EAX<imp-use,kill>

By not artificially keeping %RAX alive, we lower register pressure a bit.

The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously
55, anybody can see that. Sheesh.
