Behdad Esfahbod 044d7a06db [indic-like] Add per-lookup per-syllable flag 
This allows mix-and-matching per-syllable and other lookups.
In fact, removes the clear-syllables call completely.

That function checks for buffer->successful already.  No need
to check at call site.

Behdad Esfahbod 35d410f2ba Remove ASSERT_POD 
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything.  Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.

Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

Behdad Esfahbod 39bd07aed5 Fix bunch of unused parameter warnings

There's a few more but those are functions that need to be filled in.
