(offset_high_part, small_offset_p): New functions.
(nacro): Use them. Remove *_OB and *_DOB cases. For single-
register load and store macros, handle the 16-bit offset case first.
If a 16-bit offset is not suitable for the instruction we're
generating, load it into the temporary register using
ADDRESS_ADDI_INSN. Make the M_LI_DD code fall through into the
M_L_DAB code once the address has been constructed. For double load
and store macros, again handle the 16-bit offset case first.
If the second register cannot be accessed from the same high
part as the first, load it into AT using ADDRESS_ADDI_INSN.
Fix the handling of LD in cases where the first register is the
same as the base. Also handle the case where the offset is
not 16 bits and the second register cannot be accessed from the
same high part as the first. For unaligned loads and stores,
fuse the offbits == 12 and old "ab" handling. Apply this handling
whenever the second offset needs a different high part from the first.
Construct the offset using ADDRESS_ADDI_INSN where possible,
for offbits == 16 as well as offbits == 12. Use offset_reloc
when constructing the individual loads and stores.
(mips_ip): Set up imm_expr, imm2_expr, offset_expr, imm_reloc
and offset_reloc before matching against a particular opcode.
Handle elided 'A' constants. Allow 'A' constants to use
relocation operators.

(totimeval): Use constant 1000000 as in other functions.
(time_t_to_filetime): Remove.
(to_time_t): Change return type to time_t.
(time_as_timestruc_t): Rename filetime to systime.
(time): Ditto. Add cast.
(hires_ns::nsecs): Fix return type cast.
(hires_ms::timeGetTime_ns): Remove.
(hires_ns::prime): Remove.
(hires_ms::nsecs): Drop call to prime. Call GetSystemTimeAsFileTime
directly. Subtract FACTOR here since it's the only function needing
to do so.
(minperiod): Cosmetically change to ULONG.
(hires_ns::resolution): Fix return type cast.
(hires_ms::resolution): Simplify, rely on NtQueryTimerResolution.
* winsup.h: Align time related prototypes to above changes.

* net.cc (gen_old_if_name): New function to generate short interface
names for old pre-1.7 applications.
(get_ifs): Call gen_old_if_name for said old applications.

process.
(sigpacket::setup_handler): Fix long-standing problem where loop could exit
with lock held.

essentially guarded by thread-specific signal_arrived.
* exceptions.cc (_cygtls::handle_SIGCONT): Simplify. Eliminate lock/unlock
since code is guarded by signal_arrived.

aarch64: Add support for GNU indirect functions.
Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.
