RXv2 instructions support

[ARM] Add support for thumb1 pcrop relocations.

To support thumb1 execute-only code we need to support four new
relocations (R_ARM_THM_ALU_ABS_G0_NC, R_ARM_THM_ALU_ABS_G1_NC,
R_ARM_THM_ALU_ABS_G2_NC and R_ARM_THM_ALU_ABS_G3_NC).
These relocations allow the static linker to finalize construction
of symbol address.
Typical sequence of code to get address of the symbol foo is then
the following :
movs r3, #:upper8_15:#foo
lsls r3, #8
adds r3, #:upper0_7:#foo
lsls r3, #8
adds r3, #:lower8_15:#foo
lsls r3, #8
adds r3, #:lower0_7:#foo
This will give following sequence of text and relocations after
assembly :
4: 2300 movs r3, #0
4: R_ARM_THM_ALU_ABS_G3_NC foo
6: 021b lsls r3, r3, #8
8: 3300 adds r3, #0
8: R_ARM_THM_ALU_ABS_G2_NC foo
a: 021b lsls r3, r3, #8
c: 3300 adds r3, #0
c: R_ARM_THM_ALU_ABS_G1_NC foo
e: 021b lsls r3, r3, #8
10: 3300 adds r3, #0
10: R_ARM_THM_ALU_ABS_G0_NC foo

bfd: don't produce corrupt COFF symbol table due to long ELF file name symbols

The re-writing logic in _bfd_coff_final_link() overwrote the ".file"
part of the symbol table entry, due to not coping with the auxiliary
entry generated in all cases.

Note that while I would have wanted to add a test case,
(a) I didn't spot any one testing the base functionality here, and
(b) I wasn't able to figure out proper conditionals to use in e.g.
ld-elf/elf.exp to check for the necessary PE/PE+ support (which
varies by target).

Target remote mode fork and exec event documentation

This patch implements documentation updates for target remote mode fork and
exec events. A summary of the rationale for the changes made here:

* Connecting to a remote target -- explain that the two protocols exist.

* Connecting in target remote mode -- explain invoking gdbserver for target
remote mode, and move remote-specific text from original "Connecting to a
remote target" section.

* Connecting in target extended-remote mode -- promote this section from
"Using the gdbserver Program | Running gdbserver | Multi-Process Mode for
gdbserver". Put it next to the target remote mode section.

* Host and target files -- collect paragraphs dealing with how to locate
symbol files from original sections "Connecting to a remote target" and
"Using the gdbserver program | Connecting to gdbserver".

* Steps for connecting to a remote target -- used to be "Using the
gdbserver program | Connecting to gdbserver"

* Remote connection commands -- used to be the bulk of "Connecting to a
remote target". Added "target extended-remote" commands and information.

gdb/ChangeLog:

* NEWS: Announce fork and exec event support for target remote.

gdb/doc/ChangeLog:

* gdb.texinfo (Forks): Correct Linux kernel version where
fork and exec events are supported, add notes about support
of these events in target remote mode.
(Connecting): Reorganize and clarify distinctions between
target remote, extended-remote, and multiprocess.
Reorganize related text from separate sections into new
sections.
(Server): Note effects of target extended-remote mode.
Delete section on Multi-Process Mode for gdbserver.
Move some text to "Connecting" node.

Target remote mode fork and exec event support

This patch implements support for fork and exec events with target remote
mode Linux targets. For such targets with Linux kernels 2.5.46 and later,
this enables follow-fork-mode, detach-on-fork and fork and exec
catchpoints.

The changes required to implement this included:

* Don't exit from gdbserver if there are still active inferiors.

* Allow changing the active process in remote mode.

* Enable fork and exec events in remote mode.

* Print "Ending remote debugging" only when disconnecting.

* Combine remote_kill and extended_remote_kill into a single function
that can handle the multiple inferior case for target remote. Also,
the same thing for remote_mourn and extended_remote_mourn.

* Enable process-style ptids in target remote.

* Remove restriction on multiprocess mode in target remote.

gdb/gdbserver/ChangeLog:

* server.c (process_serial_event): Don't exit from gdbserver
in remote mode if there are still active inferiors.

gdb/ChangeLog:

* inferior.c (number_of_live_inferiors): New function.
(have_live_inferiors): Use number_of_live_inferiors in place
of duplicate code.
* inferior.h (number_of_live_inferiors): Declare new function.
* remote.c (set_general_process): Remove restriction on target
remote mode.
(remote_query_supported): Likewise.
(remote_detach_1): Exit in target remote mode only when there
is just one live inferior left.
(remote_disconnect): Unpush the target directly instead of
calling remote_mourn.
(remote_kill): Rewrite function to handle both target remote
and extended-remote. Call remote_kill_k.
(remote_kill_k): New function.
(extended_remote_kill): Delete function.
(remote_mourn, extended_remote_mourn): Combine functions into
one, remote_mourn, and enable extended functionality for target
remote.
(remote_pid_to_str): Enable "process" style ptid string for
target remote.
(remote_supports_multi_process): Remove restriction on target
remote mode.

Target remote mode fork and exec test updates

This patch updates tests for fork and exec events in target remote mode.
In the majority of cases this was a simple matter of removing some code
that disabled the test for target remote. In a few cases the test needed
to be disabled; in those cases the gdb_protocol was checked instead of
using the [is_remote target] etc.

In a couple of cases we needed to use clean_restart, since target remote
doesn't support the run command, and in one case we had to modify an expect
expression to allow for a "multiprocess-style" ptid.

Tested with the patch that implemented target remote mode fork and exec
event support.

remote.

[AArch64][PATCH 11/14] Add support for the 2H vector type.

ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. The FP16 additions to the
scalar pairwise group introduce a new vector type, 2H. This patch adds
support for this vector type to binutils.

The patch adds a new operand qualifier to the enum
aarch64.h:aarch64_opnd_qualifier. This interferes with the calculation
used by aarch64-dis.c:get_vreg_qualifier_from_value, called when
decoding an instruction. Since the new vector type is only used in FP16
scalar pairwise instructions which do not require the function, this
patch adjusts the function to ignore the new qualifier.
