The new [unique] package provides facilities for
canonicalizing values (like "interning" or "hash-consing").

Any value of comparable type may be canonicalized with the new
`Make[T]` function, which produces a reference to a canonical copy of
the value in the form of a `Handle[T]`.
Two `Handle[T]` are equal if and only if the values used to produce the
handles are equal, allowing programs to deduplicate values and reduce
their memory footprint.

//
// Keep this consistent with maxLineCol in go/scanner.
const PosMax = 1 << 30

// A Pos represents an absolute (line, col) source position
// with a reference to position base for computing relative
// (to a file, or line directive) position information.
// Pos values are intentionally light-weight so that they
// can be created without too much concern about space use.

The extra functions here are stubs to satisfy the references in the C
code generated for gcc. The build process links this stub, along with
_cgo_export.c and *.cgo2.c, into a dynamic executable and then lets
cgo examine the executable. Cgo records the list of shared library
references and resolved names and writes them into a new file
_cgo_import.go, which looks like:

		Fun:     runtimeSym(r.info, "panicrangestate"),
		ArgList: []syntax.Expr{arg},
