This change disables the test TestArenaCollision on Darwin in race mode to deal with the fact that Darwin 10.10 must use MAP_FIXED in race mode to ensure we retain our heap in a particular portion of the address space which the race detector needs. The test specifically checks to make sure a manually mapped region's space isn't re-used, which is definitely possible with MAP_FIXED because it replaces whatever mapping already exists at a given address. This change then also makes it so that MAP_FIXED is only used in race mode and on Darwin, not all BSDs, because using MAP_FIXED breaks this test for FreeBSD in addition to Darwin. Updates #26475. Fixes #29340.
