Regres: default to 100 tests per process

https://swiftshader-review.googlesource.com/c/SwiftShader/+/69209 shows the
speedup achieved by this change: from 2h1m to 7m45s.

More than 100 tests per process doesn't have a significant speedup effect,
while 10 is about 2x slower.

If 1% of tests crash we spawn roughly the same number of processes running
1 test as before. In other words it would take about 2h to run in that
case. Higher percentage crashes wouldn't slow it down further since they'd
often fall into the same "bucket". At 1000 tests per process it would only
take 0.1% crashes to reach maximum slowdown so this is not worth the
marginal speedup.
