Ulrich Weigand 8a51d8ea95 Make InstCombineCasts.cpp:OptimizeIntToFloatBitCast endian safe. ...

The OptimizeIntToFloatBitCast converts shift-truncate sequences
into extractelement operations.  The computation of the element
index to be used in the resulting operation is currently only
correct for little-endian targets.

This commit fixes the element index computation to be correct
for big-endian targets as well.  If the target byte order is
unknown, the optimization cannot be performed at all.
