Behdad Esfahbod 067225a86d [set] Optimize const page_for() using last_page_lookup caching 
Similar to previous commit.

This speeds up SetLookup benchmark by 50%, but that's because that
lookup always hits the same page...

Behdad Esfahbod c283e41ce3 [set] Optimize non-const page_for() using last_page_lookup caching

Behdad Esfahbod 4d48fae4f2 Enforce Regional_Indicators native direction to LTR 
And undo the morx direction reversal change introduced in
https://github.com/harfbuzz/harfbuzz/pull/3315
23159084b4

This fixes original bug https://github.com/harfbuzz/harfbuzz/issues/3314

And the reversion in morx code fixes regressions:

Behdad Esfahbod ec925ece05 [khmer] Reinstate a pause after basic features 
This was removed as part of 044d7a06db,
which caused the regression.  Just adding a pause fixes the shaping.
Debugged by just tracing the good/bad shaping and observing the
lookup orders intermingling in the bad shaping.

Test:
