  Place dynamic condition cleanups before branching

A dynamic user condition can create expression temporaries before the
selected variant is lowered. For example, a metadirective condition
such as:

  when(user={condition(getbool("hello"))}: barrier)

passes a character literal through an associated temporary. That
temporary belongs to evaluating the condition, so it must be cleaned
up before lowering enters the generated fir.if that selects between
variants.

Finalize the statement context after evaluating the condition and
before creating the branch. Keep the condition expression and source
location together as DynamicUserCondition, use that source for
generated operations, and add a regression for the temporary-producing
condition case.
