Chris Lattner 672452d5a0 Disable the load-shrinking optimization from looking at
anything larger than 64-bits, avoiding a crash.  This should
really be fixed to use APInts, though type legalization happens
to help us out and we get good code on the attached testcase at
least.

This fixes rdar://6836460
