gimple_has_location returns false for the return statement on both
i686 and x86_64. When I hacked SRA to set the location of return
statement to the location of the preceding statement
("<retval> = res;" or "D.1523 = res;"), the reported lines in the
warnings were consistent on both i686 and x86_64 (22 in both cases, of
course).
So making sure the two statements both have the location we want to
give in the warning is a way of dealing with this issue. To me it
even seems they do belong to the same source construct and should have
the same location.
