As Cary Countant wrote me, gold's ICF has never implemented support for call
site tables in GDB. Moreover, when Jakub designed the new call site tags, the
design hasn't been changed.

Bug 63572 depends on bug 63566, which changed state.
Bug 63566 Summary: [5 Regression] i686 bootstrap fails: ICE RTL flag check:
INSN_UID used with unexpected rtx code 'set' in INSN_UID, at rtl.h:1326

Not sure if we can do anything about this. ICF breaks this in a similar way
as tail merging does (which makes this kind of regressions older).
I'd say we should suspend this bug

For debugging most important is to get
(gdb) b foo
still work when foo was merged with bar and the program now calls bar
Similarly nice (but probably impossible) is
(gdb) b

Better testcase, where ICF actually happens.
struct S { int a; int b; int c; };
__attribute__((noinline)) static int
f1 (struct S *x)
{
static int u = 1;
int g = x-a * 7;

There's how gold's ICF works for test attached by Jakub:

gcc version 5.0.0 20141016 (experimental) (GCC)
