91c449a64a [graph] Make space_for non-recursive 
It was tail-recursive so perhaps the compiler did the same.
Anyway, make it explicit now.

70b3fbed28 [graph] Fix invalid read when map gets resized 
I don't fully understand how the old code was wrong, since
*v should be evaluated before the set() method call.
Yet this seems to fix a bug that could be reproduced
with HB_DEBUG_SUBSET_REPACK enabled and the following:

fd79c7cecd [gsubgpos] Keep another digest in the applicable_t 
The digest for all the remaining subtables combined.
The idea is to get out of the subtable look as soon as
no more can be applied.

Doesn't seem to speed up anything I tested. Going to revert.
