And add a unary op macro. Having VectorCompOp makes it easy to write
macros that work for multiple data widths, which is why it and its users
now use (dst, ...) instead of (..., dst) as in the past. I'll sort out
the other macros later now that I know the compiler handily gives
messages about the switched order (uninitialized vars etc).
This renames existing VectorCompCompare (and quaternion equivalent) to
VectorCompCompareAll and makes VectorCompCompare produce a vector of
results with optional negation (converting 0,1 to 0,-1 for compatibility
with simd semantics).
This should make maintaining them a little easier.
The copyright block in most of the new headers (execpt vector.h) reflect
when the functions in the relevant header were first created.
