  [clang] Save ShuffleVectorExpr args as ConstantExpr (#139709)

The passed indices have to be constant integers anyway, which we verify
before creating the ShuffleVectorExpr. Use the value we create there and
save the indices using a ConstantExpr instead. This way, we don't have
to evaluate the args every time we call getShuffleMaskIdx().
