[lldb-dev] increase timeout for tests?

[Pavel Labath via lldb-dev]

I think we should get some data before pulling numbers out of our sleeves.
If we can get some numbers on the slowest machine that we have around, then
we should be able to specify the timeout as some multiple of the slowest
test. For example, for me the slowest test takes around 110 seconds. The
timeout is 4 minutes (~ 2x) and I don't get tests timing out. How long does
the slowest test take for you? If we set the timeout as 3x or 4x that
number, we should create a sufficiently large buffer and still avoid
half-hour waits.
