gdb.base/async.exp: Leave gdb_protocol alone.

Many eons ago, async was only implemented in the remote target, and
you'd activate it by doing "target async" rather than "target remote".
That's long gone now, replaced by "set target-async on".

	* gdb.base/async.exp: Don't frob gdb_protocol.
gdb.base/async.exp: Don't hardcode line numbers.

	* gdb.base/async.c (main): Add "jump here" and "until here" line
	marker comments.
	* gdb.base/async.exp (jump_here): New global.
	(jump& test): Use it.
	(until_here): New global.
	(until& test): Use it.
gdb.base/async.exp: Fix stepi& test.

Currently the test assumes that "stepi" over:

 13       x = 5;

end up somewhere midline.  But, (at least) on x86, that assignment
ends up compiled as just one movl instruction, so a stepi stops at the
next line already:

 completed.
 PASS: gdb.base/async.exp: step &
 step&
 (gdb) foo () at ../../../src/gdb/testsuite/gdb.base/async.c:13
 13       x = 5;
 completed.
 PASS: gdb.base/async.exp: step &
 stepi&
 (gdb) 14         y = 3;
 completed.
 FAIL: gdb.base/async.exp: (timeout) stepi &
 nexti&
 (gdb) 16         return x + y;
 completed.
 FAIL: gdb.base/async.exp: (timeout) nexti &
 finish&
 Run till exit from #0  foo () at ../../../src/gdb/testsuite/gdb.base/async.c:16

This patch fixes it, by making sure there's more than one instruction
in that line.

	* gdb.base/async.c (foo): Make 'x' volatile.  Write to it twice in
	the same line.
gdb.base/async.exp: Use prepare_for_testing.

gdb/testsuite/

	* gdb.base/async.exp: Use prepare_for_testing.
gdb.base/async.exp: Factor out test pattern to a procedure.

All the tests here follow the same pattern (and they all have the same
problem, not fixed here yet).  Add a new procedure, factoring out the
pattern to a simple place.

gdb/testsuite/

	* gdb.base/async.exp (test_background): New procedure.
	Use it for all background execution command tests.
gdb.base/async.exp: Fix races.

This test is currently racy:

 PASS: gdb.base/async.exp: step&
 stepi&
 (gdb) 0x0000000000400547        14       x = 5; x = 5;
 completed.
 PASS: gdb.base/async.exp: stepi&
 nexti&
 (gdb) 15         y = 3;
 completed.FAIL: gdb.base/async.exp: nexti&

The problem is here:

 	-re "^$command\r\n${before_prompt}${gdb_prompt}${after_prompt}completed\.\r\n" {
 	    pass "$command"
 	}
	-re "$gdb_prompt.*completed\.$" {
 	    fail "$command"
	}

Note how the fail pattern is a subset of the pass pattern.  If the
expect buffer happens to end up with:

  "^$command\r\n${before_prompt}${gdb_prompt}${after_prompt}completed\."

that is, the final "\r\n" has't reached the expect buffer yet, but
"completed." has, then the fail pattern matches...

	* gdb.base/async.exp (test_background): Expect \r\n after
	"completed." in the fail pattern.

	* gdb.base/async.exp (step& tests): Pass explicit test messages.
gdb.base/async.exp: Enable it.

There's no reason not to enable this test anymore.

Even if the current output isn't ideal (we mess up the prompt), it's what
we have today.  We can adjust the test if the output improves.

	* gdb.base/async.exp: Remove early return.
Fix Sparc test which was failing in the presence of new v9 opcodes.

	* gas/sparc/ldd_std.d: Fix objdump invocation in order to get
	the old opcodes for the ldtw, ldtwa, stw and stwa instructions.
This patch adds support for the hyperprivileged registers %hstick_offset
and %hstick_enable to the Sparc assembler.

	* config/tc-sparc.c (hpriv_reg_table): Added entries for
	%hstick_offset and %hstick_enable.

	%hstick_enable hyperprivileged registers.

This is a fix for PR binutils/16723, where a corrupt .gnu.version_r section could
send readelf into an infinite loop.

	* readelf.c (process_version_sections): Prevent an infinite loop
	when the vn_next field is zero but there are still entries to be
	processed.
