disp-step-syscall.exp is extended for stepping over syscall instruction
in different cases, with or without displaced stepping, and stepping
over by GDBserver.
This patch rename disp-step-syscall.exp to step-over-syscall.exp to
reflect this.

We can also extend disp-step-syscall.exp to test GDBserver step over
breakpoint on syscall instruction. That is, we set a breakpoint
with a false condition on syscall instruction, so that GDBserver will
step over it.
This test triggers a GDBserver internal error, which can be fixed by
this series.

disp-step-syscall.exp was added to test displaced stepping over syscall
instructions, in which we set breakpoint on syscall instruction, and
step over it. In fact, we can extend the test to non-displaced-stepping
case. This patch wraps the test with displaced stepping on and off.
Note that the indentation and format isn't adjusted here to make this
patch easy to read. The following patch will fix the format separately.

when GDBserver steps over a thread, other threads have been suspended,
the "stepping" thread may create new thread, but GDBserver doesn't set
it suspend count to 1. When GDBserver unsuspend threads, the child's
suspend count goes to -1, and the assert is triggered. In fact, GDBserver
has already taken care of suspend count of new thread when GDBserver is
suspending all threads except the one GDBserver wants to step over by
https://sourceware.org/ml/gdb-patches/2015-07/msg00946.html
+ /* If we're suspending all threads, leave this one suspended
+ too. */
+ if (stopping_threads == STOPPING_AND_SUSPENDING_THREADS)
+ {
+ if (debug_threads)
+ debug_printf ("HEW: leaving child suspended\n");
+ child_lwp->suspended = 1;
+ }
but that is not enough, because new thread is still can be spawned in
the thread which is being stepped over. This patch extends the
condition that GDBserver set child's suspend count to one if it is
suspending threads or stepping over the thread.

R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations
retrieve the symbol address via its GOT slot. If the symbol address is
known at the link-time, we can use it directly by changing instruction
encoding. Indirect branch can only be converted to PC relative direct
branch. MOV can be changed to LEA or encoded differently with signed
address. The subset of binary operations can be encoded only with
signed address.
If undefined weak symbol is resolved to zero link-time, we can use it
as address. Zero addresss can't used with PC relative direct branch
when PIC is true since the current PC is unknown. In 64-bit, 32-bit
relocation for PC relatiave direct branch to zero may also overflow.
If this optimization causes relocation overflow, --no-relax can be used
to work around it.
