Summary: RCTCache had really bad insertion performance when the cache was full due to having to LRU-sort the entries. This was making color animations very slow. I've fixed this in two ways: 1) by removing the sort and doing a linear search to remove old entries, which changes insertion perf to O(n) in the worst case instead of O(n log n) or even (n2). 2) by reducing the size of the color cache to 128 from 1024, which should be fine for normal use, without penalising animation performance. Separately, border colors were not being retained, which caused crashes when the color cache was cleared. I've fixed that by retaining the border colors inside RCTView.
