Charles Davis 8545afe0b0 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).

Eric Christopher 87abfc506f Move SimplifyLibCalls's LibCall builders to a separate file so they 
can be used in more places.  Add an argument for the TargetData that
most of them need. Update for the getInt8PtrTy() change.  Should be
no functionality change.

Jakob Stoklund Olesen 2664d295cb 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.

Jakob Stoklund Olesen 8c5b8db5cd We don't really care about correct register liveness information after the 
post-ra scheduler has run. Disable the verifier checks that late in the game.

Wesley Peck 34004170c5 Reworking the stack layout that the MicroBlaze backend generates. 
The MicroBlaze backend was generating stack layouts that did not
conform correctly to the ABI. This update generates stack layouts
which are closer to what GCC does.

Variable arguments support was added as well but the stack layout
for varargs has not been finalized.

Chris Lattner 067459c62b Fix PR6503. This turned into a much more interesting and nasty bug. Various 
parts of the cmp|cmp and cmp&cmp folding logic wasn't prepared for vectors
(unrelated to the bug but noticed while in the code) and the code was 
*definitely* not safe to use by the (cast icmp)|(cast icmp) handling logic
that I added in r95855.  Fix all this up by changing the various routines
to more consistently use IRBuilder and not pass in the I which had the wrong 
type.

Chris Lattner 55e81eb49f 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.
