Behdad Esfahbod b87360763e [vector] Support shrinking storage if exact size provided 
Only do it if requested size is less than quarter of allocated size.

This has massive benefit during CFF subset preprocessing.

Behdad Esfahbod 8e9e94dba9 Revert "[vector] Optimize grow_vector() for size" 
This reverts commit 1dd9396c7a.

Is faster indeed.

15% on SourceHanSans/10000 benchmark.

Behdad Esfahbod 2892fc71e8 [vector] Add std::move to pop() 
This was removed in 76fc27713f,
but I believe that was faultly. It was because of a bad move
implementation in the set.

Behdad Esfahbod 76fc27713f [vector] Remove explicit std::move 
Was confusing compilers. Let them figure it out themselves.

Makes NotoNastaliqu subsetting/1000 benchmark more than twice faster:
