7abdb8ccea [base] Significant optimization of `ft_div64by32' 
We shift as many bits as we can into the high register, perform
32-bit division with modulo there, then work through the remaining
bits with long division. This optimization is especially noticeable
for smaller dividends that barely use the high register.

* src/base/ftcalc.c (ft_div64by32): Updated.

7f49111f81 [base] Avoid unnecessary long division. 
This applies to `FT_MulDiv' but not to `FT_DivFix', where overflows or
lack thereof are predicted accurately.

* src/base/ftcalc.c (ft_div64by32): Improve readability.
(FT_MulDiv, FT_MulDiv_No_Round) [!FT_LONG64]: Use straight division

441b3f3898 [truetype] Improve handling of buggy `prep' tables. 
In case of an error in the `prep' table, no longer try to execute it
again and again.  This makes FreeType handle endless loops in buggy
fonts much faster.

and `cvt_ready' are now negative if not initialized yet, otherwise
they indicate the error code of the last run.

* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
tt_size_done_bytecode, tt_size_init_bytecode,
tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset):
Updated.

* src/truetype/ttgload.c (tt_loader_init): Updated.
* src/truetype/ttinterp.c (TT_RunIns): Force reexecution of `fpgm'
and `prep' only if we are in the `glyf' table.
