Fix test crashes on AIX

Both hash_collision_bench and manifest_parser_perftest crash on AIX with

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
IOT/Abort trap (core dumped)

32-bit AIX applications by default allocates only a single 256M segment
for stack and heap for 32-bit applications, which is insufficient for
these tests. When building these tests on AIX in 32-bit mode, increase
the max number of segments so they will run without crashing.
