4f87295872 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.

ceb80b14d3 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.

f321f1f93f * add some assertions for sanity checking. 
* remove some old code that was needed when we'd put ESP in the scale instead of 
  the base of some instructions.
* Fix a bug with the P modifier in inline asm that caused us to drop it.

ea7bd9b484 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

a754f344b2 implement support for spliting and scalarizing vector setcc's. This

54c0359890 do not try to analyze bitcasts from i64 to <2 x i32> in ComputedMaskedBits. While 
we could do this, doing so requires adjusting the demanded mask and the code isn't 
doing that yet.  This fixes PR4495
