Fix false FAIL on gdb.base/stap-probe.exp, due to ICF optimization
GCC 6's ICF optimization pass is making the declaration of 'm1' and
'm2', on gdb.base/stap-probe.c, to be unified. However, this leads to
only one instance of the probe 'two' being created, which causes a
failure on the testsuite (which expects a multi-location breakpoint to
be inserted on the probe).
This patch fixes this failure by declaring a dummy variable on 'm1',
and using it as an argument to m1's version of probe 'two'. Since we
do not care about the contents of the functions nor about the
arguments of each probe 'two', this is OK.

The .exp patch is an obvious typo fix I think. The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

Fix a few gdb.base/jit-simple.exp problems
I noticed that we sometimes get this:
(gdb) print &__jit_debug_descriptor
$1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
[...]
(gdb) run
[...]
Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
Unsupported JIT protocol version 4 in descriptor (expected 1)
Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
36 return 0;
(gdb) print &__jit_debug_descriptor
$2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.
Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.
The test doesn't catch any of this because it doesn't compare
before/after addresses.
And then notice the "blah 1" test messages. "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time. :-)
The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run". However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded. (This is an old problem out of scope of this series.) If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.
Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

Fix PR11094: JIT breakpoint is not properly recreated on reruns
Even though this was supposedly in the gdb 7.2 timeframe, the testcase
in PR11094 crashes current GDB with a segfault:

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.
If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):
(gdb) maint info breakpoints
Num Type Disp Enb Address What
[...]
-8 jit events keep y <PENDING> inf 1
[...]
But that's incorrect. GDB should have managed to recreate the JIT
breakpoint's location for the second run. So the problem is
elsewhere.
The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:
static int
jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
struct jit_program_space_data *ps_data)
{
[...]
if (ps_data->cached_code_address == addr)
return 0;
[...]
delete_breakpoint (ps_data->jit_breakpoint);
[...]
ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);
Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.
The test that was originally added for PR11094 doesn't trip on this
because:
#1 - It doesn't test the case of the JIT descriptor's address _not_
changing between reruns.
#2 - And then it doesn't do "maint info breakpoints", or really
anything with the JIT at all.
#3 - and even then, to trigger the problem the JIT descriptor needs
to be in a separate library, while the current test puts it in
the main program.
The patch extends the test to cover all combinations of these
scenarios.
