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.

3d304f48ca MIPS: Only build microMIPS specific simulator functions if microMIPS support is required.
This fixes PR sim/19441.  In the MIPS simulator the microMIPS
functions in micromips.igen were not predicated on the microMIPS
models.  This was causing build issues for some target triples.
This patch sets all the microMIPS specific functions to only be built if
the micromips32, micromips64 or micromipsdsp models are used.

	PR sim/19441
	* micromips.igen (delayslot_micromips): Enable for `micromips32',
	`micromips64' and `micromipsdsp' only.
	(process_isa_mode): Enable for `micromips32' and `micromips64' only.
	(do_micromips_jalr, do_micromips_jal): Likewise.
	(compute_movep_src_reg): Likewise.
	(compute_andi16_imm): Likewise.
	(convert_fmt_micromips): Likewise.

26f8bf63bf sim: mips: delete mmu stubs to move to common sim_{read,write}
The only unique thing about mip's sim_{read,write} helpers is the call to
address_translation on the incoming address.  When we look closer at that
function though, we see it's just a stub that maps physical to virtual,
and the cache/return values are hardcoded.  If we delete this function,
we can then collapse all the callers and drop the custom sim_{read,write}
logic entirely.

Some day we might want to add MMU support, but when we do, we'll want to
have the common layers handle things so all targets benefit.
