Remove configure --disable-float4-byval

Browse Source 
This build option was only useful to maintain compatibility for
version-0 functions, but those are no longer supported, so this option
can be removed.

float4 is now always pass-by-value; the pass-by-reference code path is
completely removed.

Disable passing float4 values <quote>by value</quote>, causing them

performance, but may be needed for compatibility with very old
