[Indic] Move Halant with after-base consonants
...
Normally, we attach the Halant to the previous character and move it
with it. For after-base consonants however, the Halant "belongs" to the
consonant after, so attach it so.
This fixes Bengali sequences involving post-base consonant Ya, which
should ligate with the Halant to form Ya Phala, but previously a
reordered matras was blocking the ligation.

Bengali failures (a couple more to go).

Don't use atomic ops in hb_cache_t
...
