5a3d871831 net: allow more generous slop in Fluctuation tests
It appears that at least the OpenBSD kernel gets sloppier the longer
the timeout we give it, up to an observed overhead of around 25%.
Let's give it a little more than that (33%) in the comparison, and
also increase the growth curve to match the actual observed times
instead of exponential initial growth.

Fixes #36108

e73c6c8808 cmd/go: fix go work sync when there are zero workspace modules
go work sync panics when there are no workspace modules. This is
because the code that set the pruning mode only did so with modules
present. This change changes pruningForGoVersion to properly return
workspace pruning in workspace mode to prevent that. Another weird
scenario can happen when there are no workspace modules, but the
command-line-arguments module is created by default. Check for that
when iterating over the workspace modules to avoid trying to find the
nonexistant go.mod file for that modules.

5e774b0f5c net: simplify deadline fluctuation tests
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

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.

f6647f2e3b spec: generalize method sets and interface types to type sets
This is the first of several CLs that update the existing
Go 1.17 spec for type parameters.

This CL updates the section on method sets and interface types.
It also adds "any", "comparable" to the list of predeclared
identifiers.

0440fb8334 runtime: make faketime more robust against GC
When using faketime, only run the scavenger for one loop.
It tries to run for 1 ms, but with faketime that calculation fails.

Prohibit write barriers in the faketime write function, in case
the GC wants to print something (e.g., with GODEBUG=gctrace=1).
