Now when trying to fix *ast.BadStmt, we parse the manually extracted
expression using parser.ParseFile instead of parser.ParseExpr.
ParseFile will yield *ast.BadStmt nodes for any bad statements nested
in our first bad statement, allowing us to fix them recursively.
To turn our expression into a "valid" file we can pass to
parser.ParseFile, I wrapped it thusly:
package fake
func _() {
<our expression>
}

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.

Invert "useDeepCompletions" config flag to "disableDeepCompletion" and
separate out "disableFuzzyMatching" which reverts to the previous
prefix matching behavior.
I separated fuzzy matching tests out to a separate file so they aren't
entangled with deep completion tests. In coming up with representative
test cases I found a couple issues which I fixed:
- We were treating a fuzzy matcher score of 0 as no match, but the
matcher returns 0 for candidates that match but have no bonuses. I
changed the matcher interface so that a score of 0 counts as a
match. For example, this was preventing a pattern of "o" from
matching "foo".
- When we lower a candidate's score based on its depth, we were
subtracting a static multiplier which could result in the score
going negative. A negative score messes up future score weighting
because multiplying it by a value in the range [0, 1) makes it
bigger instead of smaller. Fix by scaling a candidate's score based
on its depth rather than subtracting a constant factor.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:
func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)
Will now give a candidate for "s.i" since its type matches the
expected type.
We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.
Deep completions are behind the "useDeepCompletions" LSP config flag
for now.

When checking if a completion candidate matches the expected type at
the cursor position, we now use types.AssignableTo instead of
types.Identical. This properly handles cases like using a concrete
type to satisfy an interface type.
Calling AssignableTo triggered some crashes related to the fake
"resolved" types we create. Their underlying type was nil, which is
not allowed. We now set their underlying type to the invalid type.
I've also rearranged things so expected type information lives in a
dedicated typeInference struct. For now there is no new information added,
but in subsequent commits there will be more metadata about the
expected type.

This change implements the find all references feature by finding all of
the uses and definitions of the identifier within the current package.
Testing for references is done using "refs" in the testdata files and
marking the references in the package.
