Skip tests on arm/mips that time out now we're running on CLoop

Unreviewed gardening.

Since the JIT is temporarily disabled on 32-bit platforms, these tests
time out on the bots and need to be disabled. There's more tests
disabled on arm because the timeout is longer on the mips bot (as the
device is slower to start with), so many of the tests don't time out
there.

* microbenchmarks/getter-richards.js: disable on arm and mips.
