When a godoc Presentation is serving a file, it will sniff its
contents to determine if it contains "human-readable" text. If
it does, then it serves the contents of the file with surrounding
HTML. SVG files should not be served with any additional HTML even
though their contents are not a binary format (just like CSS or JS
files).

Fix the following issues:
- We were trying to complete struct literal field names for
selector expressions (e.g. "Foo{a.B<>}"). Now we only complete field
names in this case if the expression is an *ast.Ident.
- We weren't including lexical completions in cases where you might be
completing a field name or a variable name (e.g. "Foo{A<>}").
I refactored composite literal logic to live mostly in one place. Now
enclosingCompositeLiteral computes all the bits of information related
to composite literals. The expected type, completion, and snippet code
make use of those precalculated facts instead of redoing the work.

If you have x == 1 || x == 2 || x == 3 || x == 4, the pass considered the set
{x==1, x==2, x==3, x==4}
and then also
{x==2, x==3, x==4}
{x==3, x==4}
Since the comparison is itself linear in the size of the set, this was overall
taking time quadratic in the length of the || or && sequence.
Worse, if it found duplicates, they'd be reported a quadratic number of times.
This CL cuts the time and output to linear by avoiding already-checked

golang.org/x/tools/go/vcs is significantly behind the upstream
cmd/go/internal/get code, and has no support for modules. It continues
to implement mechanics for GOPATH mode only.
This change is a minimal fix to get it to continue to work
in the presence of the module mode-only "mod" VCS type
(documented at https://golang.org/cmd/go/#hdr-Remote_import_paths)
by effectively implementing IgnoreMod ModuleMode behavior.
It is similar to issue golang/go#24751 and a small subset of CL 109340
that fixed it.
This helps with module adoption by reducing the harm of adding the
"mod" VCS type for vanity import paths, something that was meant to
be backwards compatible.
