cf8f00e354 [VarStore] Don't use NAN 
Is faster.

With this, I'm seeing 25 to 28% speedup in glyph_h_advances benchmark
of benchmark-font for var/hb tests.

3ab2c7935f [subset-perf] Signficiantly speed up ClassDef*::subset. 
Eliminates the usage of a glyph -> klass hash map and replaces it with a vector storing the mapping. This allows us to use the vector directly as the iterator driving the serialize. Approximately 1% speedup for Noto Nastaliq.
