b79ceac3c6 Prefer UINT_MAX instead of uint overflow. 
Also, prefer HB_FEATURE_GLOBAL_START and HB_FEATURE_GLOBAL_END.

[subset] Raise the bar in new vs old table size 
https://crbug.com/oss-fuzz/16740

This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.

Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.
