Don't pass booleans as mask types to simd clones (PR 92710)
In this PR we assigned a vector mask type to the result of a comparison
and then tried to pass that mask type to a simd clone, which expected
a normal (non-mask) type instead.
This patch simply punts on call arguments that have a mask type.
A better fix would be to pattern-match the comparison to a COND_EXPR,
like we would if the comparison was stored to memory, but doing that
isn't gcc 9 or 10 material.
Note that this doesn't affect x86_64-linux-gnu because the ABI promotes
bool arguments to ints.
