Change subject: IMPALA-5528: Add a knob to tune TCMalloc total thread caches size ...................................................................... IMPALA-5528: Add a knob to tune TCMalloc total thread caches size This change adds a new flag FLAGS_tcmalloc_max_total_thread_cache_bytes which specifies the maximum size in bytes which the total of all TCMalloc thread caches can grow to. By default, it's set to 0 and the default value in TCMalloc library is used. This change also always enables "aggressive decommit" feature in TCMalloc instead of just validating that it's enabled in the code by default. Testing done: core build; test_tpch.py with FLAGS_tcmalloc_max_total_thread_cache_bytes set.
