Apply clang fix for assertion failure building webkit2-gtk

Merge commit 30baa5d2a450 from llvm git (by Richard Smith):

  PR45879: Fix assert when constant evaluating union assignment.

  Consider the form of the first operand of a class assignment not the
  second operand when implicitly starting the lifetimes of union members.
  Also add a missing check that the assignment call actually came from a
  syntactic assignment, not from a direct call to `operator=`.
