[decycler] Implement an efficient graph cycle detector
This is an algorithm I came up with, based on the Floyd's
Tortoise-Hare constant-memory linear-time linked-list cycle-detection
algorithm.
https://en.wikipedia.org/wiki/Cycle_detection#Floyd's_tortoise_and_hare
It is linear-time and malloc-free. It *eventually* detects cycles,
not immediately.
The main different with Floyd's algorithm is that this algorithm
detects cycles when one is traversing down a graph, not just a
linked list.
Our existing cycle-detection algorithms use a set-of-integers,
either hb_set_t, or more efficient in this case, hb_map_t. Those
include at least one malloc, and as such show up on profiles.
Port hb-ot-font COLRv1 to use the decycler instead of previous
hb_map_t usage for cycle detection.
benchmark-font paint_glyph on NotoColorEmoji-Regular.ttf:
Before: 8ms; After: 5.5ms. No cycle detection: 5.5ms.
FT COLRv1 API is so slow (174ms) it's not worth porting to this.
Other graphs (VARC, etc) to be ported.
Test and documentation to be added.
