The specialized conversion functions care only
about a type's layout in memory, so e.g.
[1]string is equivalent to string.
Add types.SoleComponent to assist with such use cases,
and use it for the specialized conversion functions.
Increases the number of convTstring calls by ~1%.

'go env' is used for many quick operations, such as in go/packages to
query GOARCH and GOMOD. It often is a bottleneck; for example,
go/packages doesn't know whether or not to use Go modules until it has
queried GOMOD.
As such, this go command should be fast. Right now it's slower than it
should be. This commit adds a simple benchmark with os/exec, since we're
particularly interested in the cost of cmd/go's large init function.

This was implemented as part of go/doc, but it's going to be useful in
other packages. In particular, many packages under cmd/go like web and
vcs make somewhat heavy use of global regexes, which add a non-trivial
amount of init work to the cmd/go program.
A lazy wrapper around regexp.Regexp will make it trivial to get rid of
the extra cost with a trivial refactor, so make it possible for other
packages in the repository to make use of it. While naming the package,
give the members better names, such as lazyregexp.New and
lazyregexp.Regexp.
We're also considering adding some form of a lazy API to the public
regexp package, so this internal package will allow us to get some
initial experience across std and cmd.
For #29382.

Consistent logic for handling both duplicate map keys and case values,
and eliminates ad hoc value hashing code.
Also makes cmd/compile consistent with go/types's handling of
duplicate constants (see #28085), which is at least an improvement
over the status quo even if we settle on something different for the
spec.
As a side effect, this also suppresses cmd/compile's warnings about
duplicate nils in (non-interface expression) switch statements, which
was technically never allowed by the spec anyway.
