If an absolute directory path being listed is outside any modules,
go list -e returns a non-zero exit status and non-empty stderr, but
should suppress the error. This was causing a weird bug when golang.org/cl/186337
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.

In api/*.txt, interface declarations are represented with lines like:
pkg container/heap, type Interface interface { Len, Less, Pop, Push, Swap }
or, when they have no exported methods:
pkg go/ast, type Expr interface, unexported methods
The latter form confuses mkstdlib into thinking that it's a method
because of the extra comma, and then it skips the interface entirely.
Running this program is a matter of seconds once per release, so rather
than trying to fix the optimization, just remove it. The parsing logic
doesn't care about the extra lines.

Now when a file is deleted we force the file's packages to refresh
go/packages metadata, and kick off diagnostics.
I made a couple other changes to watched file handling:
- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.

generating completion candidates a little.
I also made a minor tweak to the snippet builder where empty

"${1}" or "${1:}", depending on if you passed a callback to
WritePlaceholder() or not.

Improve the existing fix-the-AST code to better identify the
expression following the "go" or "defer" keywords:
- Don't slurp the expression start outside the loop since the
expression might only have a single token.
- Set expression end to the position after the final token, not the
position of the final token.
- Track curly brace nesting to properly capture an entire "func() {}"
expression.
- Fix parent node detection to work when BadStmt isn't first statement
of block.
- Add special case to detect dangling period, e.g. "defer fmt.". We
insert phantom "_" selectors like go/parser does to prevent the
dangling "." from messing up the AST.
- Use reflect in offsetPositions so it updates positions in all node
types. This code shouldn't be called often, so I don't think
performance is a concern.
I also tweaked the function snippet code so it properly expands
"defer" and "go" expressions to function calls. It thought it didn't
have to expand since there was already a *ast.CallExpr, but the
CallExpr was faked by us and the source doesn't actually contain the
"()" calling parens.
Note that this does not work for nested go/defer statements. For
example, completions won't work properly in cases like this:
go func() {
defer fmt.<>
}
I think we can fix this as well with some more work.

Downranking builtins causes weird interplay with other completion
candidates due to fuzzy matching. For example:
notNil := 123
var foo *int = nil<>
ranks "notNil" before "nil" in the builtin list, which is counter
productive.
Change it to not downrank builtins. In my testing with this change,
builtins never were ranked above lexical items with similar names. I
think this is because the "natural" order of completion items puts
builtins last, and we stable sort items by score, so their relative
order is preserved.
