py/emitnative: Load and store words just once for Viper code.

Browse source 
This commit fixes two Xtensa sequences in order to terminate early when
loading and storing word values via an immediate index.

This was meant to be part of 55ca3fd675
but whilst it was part of the code being tested, it didn't end up in the
commit.
