  [c++17] Implement P0145R3 during constant evaluation.

Ensure that we evaluate assignment and compound-assignment
right-to-left, and array subscripting left-to-right.

Fixes PR47724.

This is a re-commit of ded79be, reverted in 37c74df, with a fix and test
for the crasher bug previously introduced.
