[libclc] Optimize CLC vector any/all builtins (#124568)

By using the vector reduction buitins we can avoid scalarization.
Targets that don't support vector reductions will scalarize later on
anyway. The vector reduction builtins should be well-enough supported by
the middle-end to be a generic solution.

This produces conceptually equivalent code: all vector elements are
OR'd/AND'd together and the final scalar is bit-shifted and masked to
produce the final result.

The 'normalize' builtin uses 'all' so its code has similarly improved in
places.
