Niels Dossche 803cd824e5 Optimizations for mb_trim (#12803) 
* Fast path for when there is nothing to trim in mb_trim

* Make mb_trim decide between linear search vs hash table lookup

Using empirical experiments I noticed that on my i7-4790 the hash table
approach becomes faster once we have more than 4 code points in the trim
characters, when evaluated on the worst case.

This patch changes the logic so that a hash table is used for a large
number of trim characters, and linear search when the number of trim
characters is <= 4.
