Fix the bug that can not generate func@plt
when linking a undefined function with cmodel=medium.
Add testcase.

This syntactic sugar is present in both classical and emerging
architectures, like Alpha, SPARC and RISC-V, and assembler macros
doing the same thing can already be found in the wild e.g. [1], proving
the feature's popularity. It's better to provide support directly in the
assembler so downstream users wouldn't have to re-invent this over and
over again.

Also re-order the jump/branch opcodes while at it, so that insns are
sorted in ascending order according to opcodes, and the label form
preceding the real definition.

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.
