Evaluation odering in function call arguments is implementation-dependent.
In fact, gcc evaluates bottom-top and clang does top-bottom.

I confirmed, with this change, that every getSCEV() is called idetically
between clang and gcc in the compilation of the LLVM tree.

Fixes #55283

FIXME: I didn't fix all of the matter.
