This uncovered what I think is a latent bug in the "how-did-we-never-
see-this-before" category. Does this patch look OK to you?

gdb/ChangeLog:

        * amd64-tdep.c (amd64_displaced_step_fixup): Fix the mask used to
        compute RETADDR.

gdb/testsuite/ChangeLog:

        * gdb.base/dso2dso-impl.c, gdb.base/dso2dso-impl.h,
        gdb.base/dso2dso-pck.c, gdb.base/dso2dso-pck.h, gdb.base/dso2dso.c,
        gdb.base/dso2dso.exp: New files.

Tested on x86_64-linux, no regression.

Thanks!
