New Revision: 126649

Log:
If a register input is smaller than a tied output then we extend
the input to the type of the output, and on big endian machines
perform a shift on the extended value.  This shift doesn't make
any sense to me, so remove it.  Note that clang does not perform
a shift in its corresponding logic.
