x/tools: various flakes on ppc (linux OOM-kills)

[gopherbot]

#!watchflakes
post <- builder ~ `ppc` && pkg ~ `golang.org/x/tools`

This is an amazingly broad watchflakes pattern, but I think there's something fundamentally broken about our ppc story; I don't think it's just a weak-order data race.

Issue created automatically to collect these failures.

Example (log):

=== RUN   TestGoplsSourceDoesNotCallTokenFileMethods
signal: killed

— watchflakes

Closing as ppc flake (watchflakes was reenabled, so I'm doing a batch cleanup; we'll deal with new flakes as they are refiled).
