53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

7b9d6ebb9c remove llvm.part.set.* and llvm.part.select.*. They have never been 
implemented in codegen, have no frontend to generate them, and are 
better implemented with pattern matching (like the ppc backend does
to generate rlwimi/rlwinm etc).

The blackfin processor has a legal i16 type, but only logic operations on i32.

56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

c97b778b3c Make changes suggested by Chris and eliminate newly-added raw_ostream 
hooks as they're no longer needed.

The major change with this patch is to make formatted_raw_ostream usable
by any client of raw_ostream.

2b77eef160 Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned 
value.  Adjust other code to deal with that correctly.  Make 
DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of 
this new flexibility to simplify the code and make it deal with unusual 
vectors (like <4 x i1>) correctly.  Fixes PR3037.

7452c968e4 Targets sometimes assign fixed stack object to spill certain callee-saved 
registers based on dynamic conditions. For example, X86 EBP/RBP, when used as
frame register has to be spilled in the first fixed object. It should inform
PEI this so it doesn't get allocated another stack object. Also, it should not
be spilled as other callee-saved registers but rather its spilling and restoring
are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice.

dab7b06de9 Improved tracking of value number kills. VN kills are now represented 
as an (index,bool) pair. The bool flag records whether the kill is a
PHI kill or not. This code will be used to enable splitting of live
intervals containing PHI-kills.

A slight change to live interval weights introduced an extra spill
into lsr-code-insertion (outside the critical sections). The test 
condition has been updated to reflect this.

6b04136756 Make SelectionDAG::getVectorShuffle work properly for VECTOR_SHUFFLE 
nodes with operand types that differ from the result type. (This
doesn't normally happen right now, because
SelectionDAGLowering::visitShuffleVector normalizes vector shuffles.)

7dcc37b942 Nowadays vectors are only split if they have an even 
number of elements.  Make some simplifications based
on this (in particular SplitVecRes_SETCC).  Tighten
up some checking while there.

4ac607332d dag combine sext(setcc) -> vsetcc before legalize. To make this safe, 
VSETCC must define all bits, which is different than it was documented
to before.  Since all targets that implement VSETCC already have this
behavior, and we don't optimize based on this, just change the 
documentation.  We now get nice code for vec_compare.ll

4e33115e5e Operand of asm("call") (the callee function) is represented 
as "X" constraint and "P" modifier on x86.  Make this work.
(Change may not be sufficient to fix it for non-Darwin, but
I'm pretty sure it won't break anything.)
