This CL adds a script to run vet on std and cmd.
There are a considerable number of false positives,
mostly from legitimate but unusual assembly in
the runtime and reflect packages.
There are also a few false positives that need fixes.
They are noted as such in the whitelists;
they're not worth holding this CL for.
The unsafe pointer check is disabled.
The false positive rate is just too high to be worth it.
There is no cmd/dist/test integration yet.
The tentative plan is that we'll check the local platform
during all.bash, and that there'll be a fast builder that
checks all platforms (to cover platforms that can't exec).

The asmdecl check had hand-rolled code that
calculated the size and offset of parameters
based only on the AST.
It included a list of known named types.
This CL changes asmdecl to use go/types instead.
This allows us to easily handle named types.
It also adds support for structs, arrays,
and complex parameters.
It improves the default names given to unnamed
parameters. Previously, all anonymous arguments were
called "unnamed", and the first anonymous return
argument was called "ret".
Anonymous arguments are now called arg, arg1, arg2,
etc., depending on the index in the argument list.
Return arguments are ret, ret1, ret2.
This CL also fixes a bug in the printing of
composite data type sizes.

cmd/vet's printf checker currently uses a hardcoded map of function
names to expected positions of format strings. We can be a bit more
precise than this by looking up the signature of the function, which
helps when libraries implement functions like Errorf or Logf with
extra arguments like log levels or error codes.
Specifically, the format string param is assumed to be the last string
parameter of the called function.

cp -r x/tools/cmd/vet cmd/vet without any changes.
The next change will adjust the source to use std
repo go/types and friends.
This may (temporarily) break the build; the next
commit (immediately following) will fix it. We do
it in two commits so that we can see the manual
changes.

This is a totally mechanical change.
Errors are reported for the beginning of the statement, not the end,
so the errchk markers need to be on the opening brace, not the closing
one. It seems this test was never run.

Fixes#4945.
Most examples in this issue now better, but #10 is incomplete and I'm not
certain how to reproduce it. It actually looks like a go/types problem, since
the type being reported is coming directly from that package.
Please reopen the issue if you disagree.

Also delete bogus tests for f.pkg (does the file have a package) since all

And fix test. Pointer to unsafe.Pointer tests nothing important...
Also identify the incorrect type: go/types.Type is a Stringer.

Then mark them with a build tag so they're not compiled into the binary.
They are called test_*.go rather than *_test.go because they are not

This is a simple refactoring of main.go that will enable the type checker
to be used during vetting.
The change has an unimportant effect on the arguments: it now assumes
that all files named explicitly on the command line belong to the same
package. When run by the go command, this was true already.
Also restore a missing parenthesis from an error message.

Also:
- faster code for example extraction
- simplify handling of command documentation:
all "main" packages are treated as commands
- various minor cleanups along the way
For commands written in Go, any doc.go file containing
documentation must now be part of package main (rather
then package documentation), otherwise the documentation
won't show up in godoc (it will still build, though).
For commands written in C, documentation may still be
in doc.go files defining package documentation, but the
recommended way is to explicitly ignore those files with
a +build ignore constraint to define package main.
Fixes#4806.
