c++'03 code and variadic support "needs work".

instead of new[]'d.  This greatly reduces the number of new[]'s, and guess what, 
they were all leaked.

This adds a fixme in this hunk:

   unsigned NumPackArgs = NumFlatArgs - PackBeginIndex;
+  // FIXME: NumPackArgs shouldn't be negative here???
   if (NumPackArgs)
-    PackArgs = &FlatArgs[PackBeginIndex];
+    PackArgs = FlatArgs.data()+PackBeginIndex;

where test/SemaTemplate/variadic-class-template-2.cpp is accessing the vector
out of range and NumPackArgs is negative.  I assume variadic template args are
completely hosed.

be a copy constructor (since it isn't one semantically)
and fix the ownership bits it sets to be correct!

the addressing modes don't make this trivially easy. This allows
it to avoid falling into the less precise heuristics in more
cases.

because the coalescer cleans it up.  Radar 7998853.

create a temporary copy of both the "true" and "false" results. Fixes
the Boost.Interprocess failures.

Daniel did all the hard work of tracking down the issue, I get to type
up the trivial fix for this horrible miscompile.

A partial redef now triggers a reload if required. Also don't add
<imp-def,dead> operands for physical superregisters.

Kill flags are still treated as full register kills, and <imp-use,kill> operands
are added for physical superregisters as before.

partial redefines.

We are going to treat a partial redefine of a virtual register as a
read-modify-write:

  %reg1024:6 = OP

Unless the register is fully clobbered:

  %reg1024:6 = OP, %reg1024<imp-def>

MachineInstr::readsVirtualRegister() knows the difference. The first case is a
read, the second isn't.

here already allow the promoted type to be used without further changes, so
just do the promotion.  This fixes part of pr7167.
