The previous change updated the import of golang.org/x/tools/go/types
to the standard go/types package, causing 1.4 builds to fail.
Fixes#13874.

A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.
Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.
All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

When String() was called on the maximum value of an integer type (eg
255 for uint8) this would cause an integer overflow, which would cause
an index error later in the code.
Fixed by re-arranging the code slightly.

Suggestion by dsymonds: Save code not data.
Add an extra element to the index array and an if can be eliminated.
Old generated code:
const _Day_name = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"
var _Day_index = [...]uint8{6, 13, 22, 30, 36, 44, 50}
func (i Day) String() string {
if i < 0 || i >= Day(len(_Day_index)) {
return fmt.Sprintf("Day(%d)", i)
}
hi := _Day_index[i]
lo := uint8(0)
if i > 0 {
lo = _Day_index[i-1]
}
return _Day_name[lo:hi]
}
New generated code:

Improve the generated code by using a const instead of a var for the names string.
This requires some refactoring to get neat const() and var() blocks.
Also change the generate map code go use a single sliced string, to reduce the
size of the compiled representation (only one string value).

Refactor a little to make testing easier.
Add golden tests and a check fo splitIntoRuns, which is the subtlest piece.
Still to come: execution tests.
Also fix a few issues in the generated code.

This tool creates String methods from constant definitions.
It's a time-saver designed to be used from go generate.
The methods generated are efficient, more so than one
is likely to create by hand.
Given
package date
type Day int
const (
Monday Day = iota
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
)
the command
stringer -type Day
will create the file day_string.go containing
package date
import "fmt"
var (
_Day_indexes = []uint8{6, 13, 22, 30, 36, 44, 50}
_Day_names = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"
)
func (i Day) String() string {
if i < 0 || i >= Day(len(_Day_indexes)) {
return fmt.Sprintf("Day(%d)", i)
}
hi := _Day_indexes[i]
lo := uint8(0)
if i > 0 {
lo = _Day_indexes[i-1]
}
return _Day_names[lo:hi]
}
There are several strategies for the created method chosen according to
the structure of the sequence of constants.
Handles integer types only, both signed and unsigned. That's probably
all that is needed.
Tests to follow, but the test structure will be large so sending this out
separately. The code has been heavily hand-tested but there are
some bugs. Don't depend on this until the tests are installed.
