  [libclc] Optimize isfpclass-like CLC builtins (#124145)

The builtins we were using to implement __clc_is(finite|inf|nan|normal)
-- __builtin_isfinite, etc. -- don't take vector types so we were
previously scalarizing. The __builtin_isfpclass builtin does take vector
types and thus allows us to keep things in vectors.

There is no change in codegen to the scalar versions of any of these
builtins.
