The existing implementation calls os.Chdir expecting the call not to
succeed. This change restores the original working directory in the
case that the call does succeed.

As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)
Update the Go tree to use the preferred names.
As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.
ReadDir changes are in a separate CL, because they are not a
simple search and replace.
For #42026.

The old os references are still valid, but update our code
to reflect best practices and get used to the new locations.
Code compiled with the bootstrap toolchain
(cmd/asm, cmd/dist, cmd/compile, debug/elf)
must remain Go 1.4-compatible and is excluded.
For #41190.

CL #163058 moves interpretation of platform-specific errors to the
syscall package. Package syscall errors implement an Is method which
os.IsPermission etc. consult. This results in an unintended semantic
change to the os package predicate functions: The following program
now prints 'true' where it used to print 'false':
package main
import "os"
type myError struct{ error }
func (e myError) Is(target error) bool { return target == os.ErrPermission }
func main() { println(os.IsPermission(myError{})) }
Change the os package error predicate functions to only examine syscall
errors, avoiding this semantic change.
This CL does retain one minor semantic change: On Plan9, os.IsPermission
used to return true for any error with text containing the string
"permission denied". It now only returns true for a syscall.ErrorString
containing that text.

As proposed in Issue #29934, update errors produced by the os package to
work with errors.Is sentinel tests. For example,
errors.Is(err, os.ErrPermission) is equivalent to os.IsPermission(err)
with added unwrapping support.
Move the definition for os.ErrPermission and others into the syscall
package. Add an Is method to syscall.Errno and others. Add an Unwrap
method to os.PathError and others.

Add an Unwrap method to PathError so it works with the errors.Is/As
