max_align_t

IMPALA-4480: zero_length_region_ must be as aligned as max_align_t

MemPool::TryAllocateAligned returns memory that might be that aligned,
and it returns &MemPool::zero_length_region_ when called to allocate a
block of size 0.

While I'm here, do some things to make diagnosing test failures from
terminal output easier.
