[PATCH] D13289: [libc++] Provide additional templates for valarray transcendentals that satisfy the standard synopsis

[Petr Pavlu via cfe-commits]

petpav01 added a comment.

It would be probably better if the patch changed the original templates to take only `__val_expr` as there is now no need for them to match valarray too. This should be a simple change but requires additional tests so I will wait for initial feedback that this approach is preferred.
