[Bug translator/12081] New: procfs probes don't cope well with de-duping

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

When the translator has merged identical probe bodies, the procfs probes end up
with a non-unique name for their buffers:

$ ./run-stap -e 'probe procfs("foo").read, procfs("bar").read { $value = pn() }'
-p4 --vp 0001
/tmp/stapFhIRBy/stap_10fdf6ac9d0c06eb4a65ba170795227b_1426.c:277: error:
