Bruce Mitchener 0c66043a92 [coretext] Fix memory leaks.
In `reference_table`, if the data is empty and we return early,
we still need to release the data object.

In `hb_coretext_shape`, there two edge cases where an early
return should release the attributed string.

if it ever got to 1 << 31.  Sprinkle 'u's around.

Nico Weber a7f0e25daf Remove unused HB_SHAPER_DATA_ENSURE_DECLARE lines.
The coretext_aat shaper delegates to the regular coretext_..._ensure() functions, so coretext_aat_..._ensure() functions defined by these macros are unused. The compiler warns about them, which in turn can confuse people to think that the coretext_aat_..._ensure() functions weren't called by accident.
