Bump Moar/NQP for 2x faster index and eqat operations
Bump Moar/NQP for 2x faster index and eqat operations

Speedup is for eq or index for strings of differing storage
types, or where one is a strand (most of our operations).

For eq: 1.7x when one is a strand and one is flat, and 2.5x when
both strings are flat.
For index: 2x speedup when haystack is flat and 1.5x speedup when
haystack is a strand.
