  [AIX]Generate debug info for static init related functions

Set the debug location for static init related functions(__dtor
and __finalize) so we can generate valid debug info on AIX by invoking
-g with clang or -debug-info-kind=limited with clang_cc1.

This also works for any other future targets who may use sinit and
sterm functions for static initialization, where a direct call to
dtor will be generated within finalize function body.

This patch also aims at validating that the debug info generated
is correct for AIX sinit related functions.
