Files named go.mod define a module boundary and punch a hole in the
repository when the module is fetched with go get. We had a couple in
testdata. Get rid of them.
In one case the changes I made to produce a module cache in packagestest
were enough. In the other, the test needs multiple minor/patch versions
of the same module, which we have no provision for. Rename them to
"definitelynot_go.mod" in the repo and fix it up in the test.

Add support for literal completion candidates such as "[]int{}" or
"make([]int, 0)". We support both named and unnamed types. I used the
existing type matching logic, so, for example, if the expected type is
an interface, we will suggest literal candidates that implement the
interface.
The literal candidates have a lower score than normal matching
candidates, so they shouldn't be disruptive in cases where you don't
want a literal candidate.
This commit adds support for slice, array, struct, map, and channel
literal candidates since they are pretty similar. Functions will be
supported in a subsequent commit.
I also added support for setting a snippet's final tab stop. This is
useful if you want the cursor to end up somewhere other than the
character after the snippet.

1. The parameter is a pointer to a slice.
2. The parameter is an array
3. The parameter is a function with no arguments
that returns a slice.

If we encounter `go list` errors when loading a user's package, we
should try to see if they've encountered any of our common error cases.
They are: 1) a user has GO111MODULE=off, but is outside of their GOPATH,
and 2) a user is in module mode but doesn't have a go.mod file.
Fortunately, go/packages does a great job handling edge cases so gopls
will work well for most of them. The main issue will be unresolved
imports. These show up in DepErrors in `go list`, so go/packages doesn't
propagate them through to the list of errors. This will require changes
to go/packages.

Tweak a couple things to improve how we reduce our search scope based
on remaining time budget:
- Check our budget on the first candidate rather than waiting for the
1000th candidate. If type checking is slow you can be out of budget
before you even begin.
- Reduce our budget check interval from 1000 candidates to 100
candidates. This just helps us adjust our search scope faster.
The first tweak required me to raise the completion budget for tests
because 100ms is not always enough. I moved the budget into the
completion options so that tests can raise it.

Previously we would type check all package handles as we fetched them.
This meant if you only cared about a file's primary package you would
still have to wait for all its packages to be type checked. For
example, when completing in foo.go, you would wait for [foo.go] and
[foo.go, foo_test.go] to be checked (the latter being the test
variant).
Now we don't type check packages as we put together the package
handles.

was submitted because that changed the conditions when -export was passed,
which in turn affected how we suppressed the go list -e error (because
-export causes a compile it overtriggers errors, so we explicitly
suppress errors in that case). The way the error was being suppressed,
no error was generated, and no fake package was generated (which go list
is supposed to do), so the contains query fallback code wasn't run.
