Behdad Esfahbod 8d05bf7dc0 Fix cast-align error
If compiler doesn't inline StructAtOffset, this was an error since we
only disable cast-align at call-site.  So, move the cast out.

Behdad Esfahbod 5515355367 [ot-font] Don't pre-load cmap table
Now that we have get_h_advances() and get_nominal_glyphs() implemented, the
overhead of doing a proper atomic load would be once per run, NOT once per
glyph.  So, no need to pre-load the tables to avoid that overhead.

As such, hb_ot_font_set_funcs() has become really cheap.  Can *finally* make
it be default font functions on all newly created fonts!

Behdad Esfahbod ec84460e46 [ot/ft] Implement get_nominal_glyphs() callback
Some more measurable speedup.  The recent commits' speedups are as follows:

Testing with Roboto, ****when disabling kern and liga****:

Before:

FT --features=-kern,-liga
user↦   0m0.521s

OT --features=-liga,-kern
user↦   0m0.568s

After:

FT --features=-liga,-kern
user↦   0m0.428s

OT --features=-liga,-kern
user↦   0m0.470s

So, 17% speedup.

Note that FT callbacks are faster than OT these days since we added an advance
cache to FT.  I don't think the difference is enough to justify adding a cache
to OT.

When not disabling kern, the thing is three times slower, so the speedups
are three times less impressive...  Still, 5% not bad for a codebase that I
otherwise thought is optimized out.

Note that, because of this and other optimiztions in our main shaper,
disabling kern and liga, the OT shaper is now *faster* than the fallback
shaper.  So, that's my recommendation to clients that need the absolute
fastest...

Behdad Esfahbod 13da3be0b3 [ot-font] Load hmtx/vmtx lazily
Since we have get_*_advanes() API now, the overhead is once per shape,
not once per glyph.

Only cmap is warmed-up at set_funcs() time now.
