Some repositories include tags like 'v1.0.0-rc.1+oryOS.9'.
If we were to allow such tags, they could become ambiguous: semantic
versioning defines versions that differ only in metadata to have equal
precedence, so if someone added a tag 'v1.0.0-rc.1+other' at a
different commit, then the version 'v1.0.0-rc.1' would become
ambiguous.
However, we should still allow those tags to be used to resolve
versions, and since we can even parse the underlying semantic version,
we can at least use that as the basis for a unique (and well-ordered)
pseudo-version.

Before this commit, the two logically equivalent conditionals below would
produce different output:
{{ if not .NonEmptyInterfaceTypedNil }}OK{{ else }}{{ end }}
{{ if .NonEmptyInterfaceTypedNil }}{{ else }}OK{{ end }}
The functions `not`, `or`, and `and` all use the same `truth` function, which
unwraps any concrete interface value before passing it to `isTrue`.
`if` and `with` also use `isTrue` to establish truth, but was missing the
interface indirect call.

The very first paragraph on "Package initialization" stated that
"variables are initialized in declaration order, but after any
variables they might depend on". This phrasing was easily
misread as "declaration order is the first sorting criteria"
and then contradicted what the subsequent paragraphs spelled
out in precise detail.
Instead, variable initialization proceeds by repeatedly determining
a set of ready to initialize variables, and then selecting from that
set the variable declared earliest. That is, declaration order is the
second sorting criteria.
Also, for the purpose of variable initialization, declarations
introducing blank (_) variables are considered like any other
variables (their initialization expressions may have side-effects
and affect initialization order), even though blank identifiers
are not "declared".
This CL adds clarifying language regarding these two issues
and the supporting example.
Both gccgo and go/types implement this behavior. cmd/compile
has a long-standing issue (#22326).
The spec also did not state in which order multiple variables
initialized by a single (multi-value) initialization expression are
handled. This CL adds a clarifying paragraph: If any such variable
is initialized, all that declaration's variables are initialized at
the same time.
This behavior matches user expectation: We are not expecting to
observe partially initialized sets of variables in declarations
such as "var a, b, c = f()".
It also matches existing cmd/compile and go/types (but not gccgo)
behavior.
Finally, cmd/compile, gccgo, and go/types produce different
initialization orders in (esoteric) cases where hidden (not
detected with existing rules) dependencies exist. Added a
sentence and example clarifying how much leeway compilers have
in those situations. The goal is to preserve the ability to
use static initialization while at the same time maintain
the relative initialization order of variables with detected
dependencies.

Adjust the dummy use function to a real use. As suggested by the
println calls in the test, nilptr2.go supposes to check that a
used nil pointer dereference panics. This use function is not
real enough so an optimized compiler such as gccgo could
eliminate the call.
The spec requires that even a dummy use would cause a panic.
Unfortunately, due to #31151 this is not true for gccgo at -O1 or
above.

In CL 173722, we moved the flag registration in the testing package into
an Init function. In order to avoid needing changes to user code, we
called Init automatically as part of testing.MainStart.
However, that isn't early enough if flag.Parse is called before the
tests run, as part of package initialization.
Fix this by injecting a bit of code to call testing.Init into test
packages. This runs before any other initialization code in the user's
test package, so testing.Init will be called before any user code can
call flag.Parse.
