No, that was proposed in early drafts of the standard, but was dropped in
favor of requiring "honoring of parentheses" (a la Fortran) instead.

Don't do that, use parentheses instead.
For finer-grained control you can use volatile, but that should not be
used merely to control subexpression evaluation order.
