`types.Types[types.TINTER]` is already used for `interface{}`, so we
can conveniently just extend the existing logic that substitutes
`byte` and `rune` with `uint8` and `int32` to also substitute `any`.

These tests were checking for fairly narrow timing windows, but were
running in parallel and heavily dependent on timer and goroutine
scheduling. This change eliminates unnecessary goroutines, runs the
tests sequentially (dramatically shortening the timeouts to reduce the
penalty of doing so), and uses timestamp comparison instead of
background timers to hopefully gain some robustness from monotonic
timestamps.
Many of the other tests from this package would benefit from similar
simplifications, which we can apply if and when we notice flaky
failures or want to improve the latency of running the test.

It causes a crash because of the unexpected XDOT operation. It's not
needed, since we will run ComputeAddrTaken() on function instantiations
after stenciling. And it's not always correct, since we may not be able
to distinguish between a array and a slice, if a type is dependent on a
type param.
However, we do need to call ComputeAddrTaken on instantiations created
during inlining, since that is after the main ComputeAddrTaken pass.

mutations are applied to the input, no new coverage is found the input
is reset to its initial state. This process is repeated until new
coverage is found, or the fuzz call times out.
This results in finding new coverage expanding inputs which have less
divergence from the initial input they were mutated from, which makes
traversing certain types of call graphs significantly more efficient.

This CL is a mostly clean port of CL 362801 from go/types to types2.
It deviates from go/types in some of the testing code because types2
already had made some of the changes.
It also re-introduces some empty lines that got lost in earlier CLs.
