[Bug c/23629] New: -finstrument-functions + -finline-functions produces incorrect output.

When a function is inlined, the corresponding calls to
__cyg_profile_func_{enter,exit} are passed the address of caller.

Below is an example. Addresses shown in "Enter"/"Exit" messages 
all point to main().
If you add -fno-inline-functions, then this problem goes away.

----- Makefile ------
CC=gcc-4.0.1
all: blah.o lib.o
        $(CC) -o a.out $^
blah.o: blah.c
        $(CC) -O3 -finstrument-functions -c $^
lib.o: lib.c
        $(CC) -O3 -c $^
------ blah.c -------
#include <stdio.h>
int Foo() { return 900; }
int Bar() { return Foo() + 10; }
int main() { printf("Value is %d\n", Bar()); }
------ lib.c --------
#include <stdio.h>
__cyg_profile_func_enter(void *this_fn, void *call_site) { printf("Enter %p\n",
this_fn); }
__cyg_profile_func_exit(void *this_fn, void *call_site) { printf("Exit %p\n",
this_fn); }
