If nil is provide as opt to the internal/imports package, use the

Also check separately that Env is non-nil, as this would also cause

Refactors somepath to print an adjacency list from "from" to "to", instead of
just the nodes. This allows other tools like modgraphviz to print the subgraph.
This is a breaking change. The previous behavior returned vertices; now it
returns edges. If you relied on the previous behavior, use:

If a user runs a file= query for a source that doesn't exist,
and they are outside of a module, fill in the GoSources for the
empty package that go list returns, so the overlay can be applied.
Also add a hack for the case where go list can't determine the compiler
(gc or gccgo) a user is using because
go list -f "{{context.Compiler}}" -- unsafe
doesn't work. If go list complains that a user is outside a module,
we'll give ourselves flexibility to guess things because there's
no right answer. So we'll guess that the compiler is gc.

On MacOS the default open file limit is 256 files per process. For big
projects this could cause issues when reading all files (more or less)
at the same time.
By moving up the `parseLimit` so the reading of the file is only done
when it is allowed to start parsing the file, we stay well below the 256
files per process (as the `parseLimit` is currently set to 20).
Since `parseLimit` is actually only used to limit IO access, let's also
rename the const to `parseLimit`.

The `files` slice is used twice. First it's used to get all results from `ph.Parse`, and then it's reused to filter all `nil` values (which may have been returned by the `ph.Parse` method).
After the loop to "filter" out all the `nil` values, we also need to strip the remaining values.
I also changed the ordering so that we first check the errors and
only then perform this loop. That way the code will return earlier
when the context was canceled.
Partially fixes#33531 by prevention the panic reported in that issue.

The bug manifests itself when a non-existent file is passed in as an
argument to gopls, causing a nil pointer dereference panic. This is due
to an attempt to reference the "mapper" attribute, which is not set if
the file is not found.
The resolution is to check for an informative error that is set on the
file instance after "getFile" is called and return it immediately to the
caller to allow the error to propagate up to the main() function and
print the error to stdout.
Testing:
--------

The old code didn't stop after finding the fallthrough target, always
walking the entire list to the top. This would effectively break
fallthroughs, constructing an invalid graph, as the fallthrough target
would never be found.
The fix brings the loop condition in line with all the other
stack-walking loop conditions in the surrounding code, which abort
once the target block has been found.
Alternatively, the entire loop could been omitted, as 'fallthrough'
has to be the last statement in a case body and thus always refers to
the immediate element on the stack. However, since the builder already
handles malformed ASTs as gracefully as possible, it seemed better to
keep the loop and to construct a slightly less wrong graph in the
presence of malformed ASTs.
Before the fix, the following code
func fn(x int) {
for {
switch x {
case 1:
println("case 1")
fallthrough
case 2:
println("case 2")
}
}
}
would result in the following graph. Note the presence of an
undefined.branch block.
.0: # entry
succs: 1
.1: # for.body
x
1
succs: 4 6
.2: # for.done
.3: # switch.done

println("case 1")

2
succs: 5 9
.7: # undefined.branch
.8: # unreachable.branch

After the fix, this graph is computed instead:
.0: # entry
