314fef6127 Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This 
is a workaround for <rdar://problem/7672401/> (which I filed).

This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

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.

18fdabadca Fix PR6497, a bug where we'd fold a load into an addc 
node which has a flag.  That flag in turn was used by an
already-selected adde which turned into an ADC32ri8 which
used a selected load which was chained to the load we
folded.  This flag use caused us to form a cycle.  Fix
this by not ignoring chains in IsLegalToFold even in
cases where the isel thinks it can.

b58a59b3c1 For SJLJ exception handling, make sure that all calls that are not marked 
as nounwind are marked with a -1 call-site value. This is necessary to, for
example, correctly process exceptions thrown from within an "unexpected"
execption handler (see SingleSource/Regression/C++/EH/expection_spec_test.cpp).

57bf8a483e change the new isel matcher to emit ComplexPattern matches 
as the very last thing before node emission.  This should
dramatically reduce the number of times we do 'MatchAddress'
on X86, speeding up compile time.  This also improves comments
in the tables and shrinks the table a bit, now down to 
80506 bytes for x86.

05bdcbb1ae Re-apply r97667 but with a little bit of thought put into the patch. This implements a special DenseMapInfo trait for DenseMap<MachineInstr*> that compare the value of the MachineInstr rather than the pointer value. Since the hashing and equality test functions ignore defs it's useful for doing CSE kind optimization.
