Hi!
I've backported a couple of patches to 4.5 branch and committed them
after bootstrapping/regtesting on x86_64-linux and i686-linux.
Additionally, I've added testcase for PR fortran/48117
to 4.5 (where it is newly fixed) and 4.6/4.7 (where it has been
fixed quite some time ago already by Richard during MEM_REF fixing).
