Fix nested patterns in rustboot
The code for taking pattern-bound variables was being interspersed with pattern code, so that if a nested pattern failed partway through, a variable would be taken but never dropped (because the drop code is inside the block representing the action for the pattern). For example, in the pattern foo(?i, bar(some[t](_)), _), if the scrutinee was foo(x, bar(none[t]), y), the variable i would be taken but never dropped. The patch fixes this bug.
