We've observed empirically that giving Impala 80% of system memory
doesn't leave enough room for the minicluster and ASAN overhead, leading
to the OOM killer striking during test runs (sometimes). This commit
reduces the threshold to 70%.
This commit also reduces the memory usage of semi-joins-exhaustive.test
by roughly halving the number of records it deals with. This was
necessary for tests to pass on a machine with 32GB of RAM.
Testing: I've run the ASAN build (more) happily with this change.
I've run exhaustive tests on a 32GB machine.
