Merge #21317: util: Make Assume() usable as unary expression
fa4cebadcffd9112da4b13c7cc7ccf21e2bee887 util: Make Assume() usable as unary expression (MarcoFalke)
Pull request description:
Assume shouldn't behave different at the call site depending on build flags. Currently compilation fails if it is used as expression. Fix that by using the lambda approach from `Assert()` without the `assert()`.
