Chris Lattner 02b0df5338 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.
