  [clang] Fix isConstantInitializer handling of transparent init lists. (#148030)

Transparent InitListExprs have different semantics, so special-case them
in Expr::isConstantInitializer.

We probably should move away from isConstantInitializer, in favor of
relying more directly on constant evaluation, but this is an easy fix.

Fixes #147949
