40ca30a82b [subset] Improve GSUB closure memoize algorithm 
Instead of memoizing the tuple of <lookup-idx,current-glyphs>, use a mapping of
lookup-idx->current-glyphs instead. Saves some work. Speeds up 5%ish on
NotoNastaliqUrdu-Regular.

subset: remove assert to handle HVAR direct mapping 
It looks like this was (at least partially) implemented in
f01c86ca9b

Should fix https://github.com/fonttools/fonttools/issues/1237

I'm still not sure about that "File a bug." when AdvWidthMap is None,
but either LsbMap or RsbMap are not None..

And we still need to add tests for this though.

28bb992c1f replace int(round(...)) with round(...) 
We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.

c0d672ba70 [subset] return value from _DehintingT2Decompiler.op_hintmask 
The `_SimpleT2Decompiler.execute` method expects that handlers for
hintmask/cntrmask operators return a tuple of (hintMaskBytes, index).
The index value is used to skip to the next token following the
hintmask bytes.
However, the `_DehintingT2Decompiler.op_hintmask` method was returning
None, thus the hintmask bytes were evaluated as the following token
instead of being consumed as such; but since in legacy python 2
`isinstance(token, basestring)` is True for both operators and
hintmask bytes, the latter might sometimes be wrongly interpreted
as operators!

For example, the hintmask bits '0110111101110010', encoded as a
bytes string `'\x6f\x72'` was being confused for the unimplemented
`'or'` operator...
