Speed up ivfflat build: use float instead of double for dot product ( #180 )
...
calculation
On ARM this makes CPU using vector multiply-add instruction (fmadd)
instead of vector multiplication + conversion to double + addition
(fmul + fcvt + fadd) at each vector dimension.
Output of distance functions and calculations that are are done once
per vector pair are left double as this don't make speed difference
and for compatibility.

Check bounds unconditionally in array_to_vector(). ( #127 )
...
Presently, array_to_vector()'s call to CheckDim() is skipped when typmod != -1, which allows for bypassing VECTOR_MAX_DIM. To fix, call Check[Expected]Dim() unconditionally. CheckExpectedDim() takes no action when typmod == -1, so there's no need to guard it with an 'if' statement.
