4b9f5ef605 [feaLib] More efficient inline format 4 lookups 
With this patch we will now reuse lookups more frequently when a
contextual lookup has inline ligature substitution rules.

[feaLib] Don’t modify variable anchors in place (#3717) 
When passing a parsed feature file that has variable anchors to
addOpenTypeFeatures(), builder would modify the anchors in place and
discard the variations, which break any subsequent use of the feature
file.

I encountered this building a font that has variable cursing anchors
with ufo2ft. The cursFeatureWriter would write the variable anchors, but
then when kernFeatreWriter compiles the file to get GSUB closure, the
variation would be dropped from the anchors, and later when when the
feature data is compiled into the font, the anchors would be compiled
without variations.

subset_test: add failing test to reproduce issue #3616 
If we subset this test font (a subset of Google Fonts' Andika-Regular.ttf) and request to keep 'cv43', only the FirstParaUILabelNameID (324) is currently kept, the other two (325 amd 326) get incorectly dropped.
All referenced nameIDs should be kept.

This will be fixed with https://github.com/fonttools/fonttools/pull/3617

```
>       assert nameIDs == keepNameIDs
E       assert {0, 1, 2, 3, 4, 5, 6, 321, 322, 323, 324} == {0, 1, 2, 3, 4, 5, 6, 321, 322, 323, 324, 325, 326}
E         Extra items in the right set:
E         325
E         326
E         Full diff:
E         - {0, 1, 2, 3, 4, 5, 6, 321, 322, 323, 324, 325, 326}

on the broken existing behavior.
