Behdad Esfahbod be89919a70 [gvar] is_valid() remove a check
I don't know why this check was there, but it doesn't make sense
because that function never returns 0 / false.

Behdad Esfahbod 28e767ddea [subset-cff] Really optimize op_str_t / parsed_cs_op_t layout
Now parsed_cs_op_t and op_str_t are both 16 bytes.

Saves another 7% in SourceHanSans/10000 benchmark.

Behdad Esfahbod 2d5ee23731 [subset-cff] Readjust parsed_cs_op_t
Now it doesn't matter anymore since op_str_t is adjusted and
is 16 bytes with 8byte alignment.
