  Log Message:
  -----------
  [CodeGen] Simplify the way lifetime of block captures is extended

Rather than pushing inactive cleanups for the block captures at the
entry of a full expression and activating them during the creation of
the block literal, just call pushLifetimeExtendedDestroy to ensure the
cleanups are popped at the end of the scope enclosing the block
expression.
