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. gdb/ChangeLog: Update copyright year range in all GDB files.

This state is maintained in host byte order. The

fetch/store register functions must translate between host
|
|
byte order and the target processor byte order.
|

Keeping this data in target byte order simplifies the register

read/write functions. Keeping this data in native order improves

the performance of the simulator. Simulation speed is deemed more
