Simon Pilgrim fe9fa7314c [X86][SSE] Regenerate vsplit and tests 
To make it more obvious how bad some of that truncation code is....

Paul Redmond 62f840f46a Improve the widening of integral binary vector operations 
- split WidenVecRes_Binary into WidenVecRes_Binary and WidenVecRes_BinaryCanTrap
  - WidenVecRes_BinaryCanTrap preserves the original behaviour for operations
    that can trap
  - WidenVecRes_Binary simply widens the operation and improves codegen for
    3-element vectors by allowing widening and promotion on x86 (matches the
    behaviour of unary and ternary operation widening)
- use WidenVecRes_Binary for operations on integers.

Benjamin Kramer a9f265ee98 Harden test so it's not affected by changes to compare lowering. 
This only failed on hosts that don't have SSE41.

Nadav Rotem 486ff59a9f Enable element promotion type legalization by deafault. 
Changed tests which assumed that vectors are legalized by widening them.

Chris Lattner ff392ab3ed now that generic vector types aren't selected onto MMX registers, these 
tests don't need -disable-mmx.

Mon P Wang 4f45512c23 It seems better to scalarize vectors of size 1 instead of widening them. 
Add support to widen SETCC.
