Bug #16764: Module.const_source_location does not work on autoloaded constants

[exterm (Philip Müller)]

As we found when trying out const_source_location on a Rails project, it breaks when used on autoloaded constants.

Example:

$ cat foo.rb
autoload :Bar, './bar'

Bar

puts Module.const_source_location("Bar")

Returns foo.rb:3, when it should return bar.rb:1.

[nobu (Nobuyoshi Nakada)]

• Backport changed from 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN to 2.5: REQUIRED, 2.6: REQUIRED, 2.7: REQUIRED

Prior to 2.6 don't have Module#const_source_location, but redefinition warning message has this location.
