Damien George bbe8d51bd9 py/map: Add fast-path for hashing of map index when it is a qstr.
Map indicies are most commonly a qstr, and adding a fast-path for hashing
of a qstr increases overall performance of the runtime.

On pyboard there is a 4% improvement in the pystone benchmark for a cost
of 20 bytes of code size.  It's about a 2% improvement on unix.
