This change does not complete the work to handle snapshots correctly,
but it does implement the behavior of re-building the snapshot on each
file invalidation.
It also moves to the approach of caching the FileHandles on the snapshot,
rather than in the goFile object, which is now not necessary.
Finally, this change shifts the logic of metadata invalidation into the
content invalidation step, so there is less logic to decide if we should
re-load a package or not.

cases like:
type myStruct struct { i i<> }
Also, fix a check for anonymous fields to make sure the field is
actually embedded. This fixes cases like this to properly have no
completions:
type myStruct struct { i<> i }
where this will still give type name completions:
type myStruct struct { i<> }

Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:
http.Handle("/", http.FileServer(<>))
will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.

In it previous implementation, tool.Main was meant to be called from
an applications main(). If it encountered an error it would print the
error to standard error and exit with a non-zero status (2).
It is also called recursively and in various test functions.
Exiting on an error makes testing difficult, unnecessarily.
This change breaks the functionality into to parts: an outer
tool.MustMain() that is intended to be called by main() functions and
an inner Main that is used by MustMain() and by test functions.
None of the existing test functions use Main()'s error value, but the
failure case tests for the command line invocation of rename (#194878)

We were recursing infinitely in cases like this:
switch true {
case true:

}
There were three things that came together to cause this:
1. We recently starting recursively fixing broken go/defer statements.
2. In this case we were failing to swap in the correct ast.Node in for
the *ast.BadStmt because we were only looking
for *ast.BlockStmt (and *ast.CaseStmt has no block).
3. After 2), we weren't returning an error so the fix() code thought
it should recurse.
Fix 2) by using reflection to swap AST nodes in a generic way. Perhaps
a bit overkill in this case, but I happened to have already written
this for an upcoming change, so I just pulled it in to fix this bug.
Fix 3) by returning an error if we fail to swap the AST nodes.
