bf484e9348 sim: Allow toggling of quiet NaN-bit semantics
IEEE754-1985 specifies the top bit of the mantissa as an indicator
of signalling vs. quiet NaN, but does not define the precise semantics.
Most architectures treat this bit as indicating quiet NaN, but legacy
(pre-R6) MIPS goes the other way and treats it as signalling NaN.

This used to be controlled by a macro that was only defined for MIPS.
This patch replaces the macro with a variable to track the current
semantics of the NaN bit and allows differentiation between older
(pre-R6) and and newer MIPS cores.

sim/common/ChangeLog:
	* sim-fpu.c (_sim_fpu): New.
	(pack_fpu, unpack_fpu): Allow reversal of quiet NaN semantics.
	* sim-fpu.h (sim_fpu_state): New struct.
	(_sim_fpu): New extern.
	(sim_fpu_quiet_nan_inverted): New define.

sim/mips/ChangeLog:
	* cp1.h (fcsr_NAN2008_mask, fcsr_NAN2008_shift): New.
	* mips.igen (check_fpu): Select default quiet NaN mode
	for legacy MIPS.
	* sim-main.h (SIM_QUIET_NAN_NEGATED): Remove.

42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

8acc9f485b Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
