alloca: add an overflow check too

Of course, alloca() shouldn't be used with anything that can grow
without bounds anyway, but let's better safe than sorry, and catch this
early.

Since alloca() is not supposed to return an error we trigger an
assert() instead, which is still better than heap trickery.
