Simon Pilgrim 0fee3372c9 [X86][SSE] Dropped -mcpu from bitcast+setcc tests 
Use triple and attribute only for consistency

Added SSE2/AVX tests on 256-bit vectors to test PACKSS behaviour

Zvi Rackover 7693733e80 [X86] Match bitcast of vxi1 to pmovmsk 
Summary:
Add an early combine to match patterns such as:
  (i16 bitcast (v16i1 x))
  ->
  (i16 movmsk (v16i8 sext (v16i1 x)))

This combine needs to happen early enough before
type-legalization scalarizes the result of the setcc.
