Various minor cctest fixes to make ASAN a bit happier.

   * Running with ASAN needs more stack, so don't set resource constraints too
     tight.

   * Checking boot time memory usage doesn't make sense when running with ASAN,
     it eats tons of memory for itself.

   * Fixed a malloc/delete[] mismatch: Not surprisingly, the pointer wrapped by
     a SmartArrayPointer should better be allocated by, well, NewArray...

Even with these 3 fixes, we still have a few failures when running our test
suite with ASAN. Most of them are either timeouts or failures caused by greatly
increased stack usage.
