7d1a7c0417 Change the marker byte for stubs from 0xcd to 0xce (another form of 
interrupt instruction, which shouldn't arise any other way).  0xcd is
also used by JITMemoryManager to initialize the buffer to garbage,
which means it could appear following a noreturn call even when
that is not a stub, confusing X86CompilationCallback2.  PR 4929.

e4863f4759 Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex. This occurs for 
VLDM/VSTM instructions, and without this check, the code assumes that an
offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
however, silently drops the offset, producing incorrect code.  Since the
address register in this case is either the stack or frame pointer, the
spill location ends up conflicting with some other stack slot or with
outgoing arguments on the stack.

e3394d4a49 When a constant's type is refined, update the constant in place 
instead of cloning and RAUWing it.

 - Make AbstractTypeUser a friend of Value so that it can offer
   its subclasses a way to update a Value's type in place. This
   is better than a universally visible setType method on Value,
   and it's sufficient for the immediate need.

 - Eliminate the constant "convert" functions. This eliminates a
   lot of logic duplication, and fixes a complicated bug where a
   constant can't actually be cloned during the type refinement
   process because some of the types that its folder needs are
   half-destroyed, being in the middle of refinement themselves.

 - Move the getValType functions from being static overloaded
   functions in Constants.cpp to be members of class template
   specializations in ConstantsContext.h. This means that the
   code ends up getting instantiated twice, however it also
   makes it possible to eliminate all "convert" functions, so
   it's not a big net code size increase. And if desired, the
   duplicate instantiations could be eliminated with some
   reorganization.
