The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT.
...
This check-in adds a flag to OP_SeekGE such that it fails immediately if
the key is not equal, then jumps over the OP_IdxGT, saving a call to the key
comparison functions. Consider this check-in a proof-of-concept. It needs
improvement before going on trunk. Some tests fail, but only because they
new use fewer key comparisons than expected (which is a good thing!).
