#5867: Include use site of deprecated identifiers in deprecation warnings

------------------------------+---------------------------------------------
Currently a deprecation warning reports the line of the import statement
that brings the deprecated identifier into scope. I think it would be
useful to print the line where the identifier is used, instead.
Steps to reproduce:
{{{
module Foo where
import Bar
foo = bar
}}}
{{{
module Bar where
bar = 23
{-# DEPRECATED bar "use baz instead" #-}
}}}
Expected result:
{{{
Foo.hs:3:1:
Warning: In the use of `bar'
(imported from Bar):
Deprecated: "use baz instead"
}}}
Actual result:
{{{
Foo.hs:2:1:
Warning: In the use of `bar'
(imported from Bar):
Deprecated: "use baz instead"
}}}
