c4db4e5105 [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bit 
and 256-bit forms.  Because the number of elements in a vector
      does not determine the vector type (4 elements could be v4f32 or
      v4f64), pass the full type of the vector to decode routines.

- Add appropriate TableGen patterns for fadd, fsub, fmul.
- Add .f32 as the PTX type for the LLVM float type.

  to accept the float type.
- Add appropriate test cases.

7466678003 Add some DAGCombines for (adde 0, 0, glue), which are useful to optimize legalized code for large integer arithmetic. 
1. Inform users of ADDEs with two 0 operands that it never sets carry
2. Fold other ADDs or ADDCs into the ADDE if possible

It would be neat if we could do the same thing for SETCC+ADD eventually, but we can't do that in target independent code.

8fbbdca45c Set NumSignBits to 1 if KnownZero/KnownOne are being zero extended. In theory it 
is possible to do better if the high bit is set in either KnownZero/KnownOne, but
in practice NumSignBits is always 1 when we are zero extending because nothing
is known about that register.

107d366df7 Tweak the register allocator priority queue some more. 
New live ranges are assigned in long -> short order, but live ranges that have
been evicted at least once are deferred and assigned in short -> long order.

Also disable splitting and spilling for live ranges seen for the first time.

The intention is to create a realistic interference pattern from the heavy live
ranges before starting splitting and spilling around it.
