History
Chris Lattner 6745191070 Teach instcombine to transform a bitcast/(zext|trunc)/bitcast sequence 
with a vector input and output into a shuffle vector.  This sort of 
sequence happens when the input code stores with one type and reloads
with another type and then SROA promotes to i96 integers, which make
everyone sad.

This fixes rdar://7896024
