[Bug translator/5076] New: detect both inlined and non-inlined function instances

[fche at redhat dot com]

See http://sourceware.org/ml/systemtap/2007-q3/msg00726.html

We need to warn or fail upon a .return probe of a function that is inlined
in some cases and not inlined in others.

Maybe the solution to this one is to accept (and confirm) that .function.call and
.function.return probes match up, rather than .function and .function.return.

Any extras (inlined instances) would not show up under .call, so they should not
need special treatment like warnings/etc. for .return probes.

This issue appears to have been fixed in several different ways,
including by warnings for inline-.return probes.  As for the originally
reported test case, we do accept the .return probe on the non-inlined
copy of the function.

% stap -p2 -e 'probe module("nfs").function("nfs_check_flags").return {
println($return) }'
# functions
_dwarf_tvar_get_return_0:long ()
# probes
module("nfs").function("nfs_check_flags@fs/nfs/file.c:107").return /*
pc=.text+0x5040 */ /* <- module("nfs").function("nfs_check_flags").return */
