Merge in updates for mipsn32 and 32-bit arm.

Browse source 
- Brings in upstream commits to fix debugging on mipsn32 (properly parsing
  registers and signal information in core dumps as well as unwinding across
  signal frames)
- Brings in upstream commits for reworked ARM support.  Compared to the
  existing patch-armfbsd, this version includes generic FreeBSD target
  support (auxv, thread names from cores, $_siginfo, syscall names, etc.)
  as well as VFP support and an unwinder for signal frames.

commit 12c4bd7f53e9cefcf7c3a7f8cbf9e552526cb963
Author: John Baldwin <jhb@FreeBSD.org>
Date: Thu Oct 5 09:50:01 2017 -0700
Handle FreeBSD-specific AT_EHDRFLAGS and AT_HWCAP auxiliary vector types.
FreeBSD recently added two additional ELF auxiliary vectors. FreeBSD's
AT_HWCAP uses a different number compared to AT_HWCAP on Linux as the
numerical value was already in use for a different vector on FreeBSD.
include/ChangeLog:
* elf/common.h (AT_FREEBSD_EHDRFLAGS, AT_FREEBSD_HWCAP): Define.
gdb/ChangeLog:
* fbsd-tdep.c (fbsd_print_auxv_entry): Handle AT_EHDRFLAGS and
AT_HWCAP.

commit 544c67cda1686c1b204cb96c0d7885b08d37b8d6
Author: John Baldwin <jhb@FreeBSD.org>
Date: Fri Oct 6 11:41:45 2017 -0700
Account for padding in FreeBSD/mipsn32 NT_PRSTATUS notes.
Add a new ELF backend method to grok FreeBSD NT_PRSTATUS core dump
notes. Define a method for MIPS N32 to override the default
elfcore_grok_freebsd_prstatus that accounts for additional padding
between pr_pid and pr_reg that is not present in other 32-bit FreeBSD
platforms.
* elf-bfd.h (struct elf_backend_data): Add
`elf_backend_grok_freebsd_prstatus'.
* elf.c (elfcore_grok_freebsd_note): Call
`elf_backend_grok_freebsd_prstatus' to handle NT_PRSTATUS if
present.
* elfn32-mips.c (elf_n32_mips_grok_freebsd_prstatus): New
function.
(elf_backend_grok_freebsd_prstatus): Define.
* elfxx-target.h (elf_backend_grok_freebsd_prstatus): Define.
(elfNN_bed): Initialize `elf_backend_grok_freebsd_prstatus'.

commit a181c0bf74
Author: John Baldwin <jhb@FreeBSD.org>
Date: Mon Oct 9 09:54:42 2017 -0700
Use gdbarch_long_bit to determine layout of FreeBSD siginfo_t.
FreeBSD architectures are either ILP32 or LP64 resulting in two
different layouts for siginfo_t. Previously, the 'bits_per_word'
member of bfd_arch_info was used to determine the layout to use for a
given FreeBSD architecture. However, mipsn32 architectures inherit
from a 64-bit mips architecture where bits_per_word is 64. As a
result, $_siginfo was not properly extracted from FreeBSD/mipsn32 core
dumps. Fix this by using gdbarch_long_bit instead of 'bits_per_word'
to determine if a FreeBSD architecture is ILP32 or LP64.
gdb/ChangeLog:
* fbsd-nat.c (fbsd_siginfo_size): Use gdbarch_long_bit.
(fbsd_convert_siginfo): Likewise.
* fbsd-tdep.c (fbsd_core_xfer_siginfo): Likewise.

commit a80a647180bf92692e0f01efe7b323afe7d317c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Thu Oct 5 09:50:01 2017 -0700
Add a signal frame unwinder for FreeBSD/mipsn32.
The N32 signal frame uses an identical layout to N64, so reuse the N64
handler. The N32 signal trampoline does use one different instruction
relative to N64, so a separate tramp_frame is required.
gdb/ChangeLog:
* mips-fbsd-tdep.c (MIPS_INST_ADDIU_A0_SP_N32): Define.
(mipsn32_fbsd_sigframe): Define.
(mips_fbsd_init_abi): Install mipsn32_fbsd_sigframe unwinder
for FreeBSD/mipsn32.
