gas: pru: Add flag to select core revision
Add new command line option to select PRU core revision to assemble for.
This new option is used to limit the available opcodes to what the
selected revision supports.

gas: pru: Add TSEN and MVI instructions
Add support for TSEN and MVI instructions to GAS and libopcodes.
TSEN is available in newer PRU core revisions, and can be used to
implement multitasking.  MVI allows indirectly addressing CPU registers
using a pointer in R1 register.

c8f306af2f Update year range in copyright notice of binutils files
Avoid warnings about invalid escapes in etc/update-copyright.py by
using raw strings, add BinutilsFilter to skip psql.rc and add
"Kalray SA." as another copyright holder.

fd67aa1129 Update year range in copyright notice of binutils files
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:

1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
   author I haven't committed, 'Kalray SA.', to cover gas testsuite
   files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

d87bef3a7b Update year range in copyright notice of binutils files
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

a2c5833233 Update year range in copyright notice of binutils files
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
