Evan Cheng ede2ce71aa Fix up support for OptionalDefOperand when it defaults to an actual register def. I need this to get ready for major Thumb1 surgery.

David Greene 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.

Evan Cheng f075943584 Remove TargetInstrInfo::CommuteChangesDestination and added findCommutedOpIndices which returns the operand indices which are swapped (when applicable). This allows for some code clean up and future enhancements.

Eli Friedman 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.

Evan Cheng 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.

Lang Hames 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.

Dan Gohman 6b04136756 Make SelectionDAG::getVectorShuffle work properly for VECTOR_SHUFFLE

Duncan Sands 7dcc37b942 Nowadays vectors are only split if they have an even

Chris Lattner 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

I'm pretty sure it won't break anything.)

Sanjiv Gupta 031bbef528 if the terminator is a branch depending upon the side effects of a
previous cmp; a copy can not be inserted here if the copy insn also has
 side effects. We don't have access to the attributes of copy insn here;
 so just play safe by finding a safe locations for branch terminators.

Tilmann Scheller aea6059ed4 Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed arguments in a vararg call.
With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put 
into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack.

The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list.
