Improve the performance of reflective operations.
Common dex index lookups require a number of different types to be constructed,
implement short-cuts that avoid the intermediate data types.
Refactor reflective operations to use dex methods that don't require temporary
objects.
Note: this change adds an empty short array to Dex, this code can't appear in
libcore.util as Dex doesn't always come with libcore.util.
