read-cache: force split index mode with GIT_TEST_SPLIT_INDEX
This could be used to run the whole test suite with split
indexes. Index splitting is carried out at random. "git read-tree"
also resets the index and forces splitting at the next update.
I had a lot of headaches with the test suite, which proves it
exercises split index pretty good.
