Some of the TC_START_LABEL implementations need to adjust the end of
the symbol, when a colon doesn't mean a label definition. That means
they need access to nul_char both the restore the NUL location (it may
be a quote rather than a colon) and to store the new nul_char. Others
need adjusting to step over a potential trailing quote.

Auto-litpools is the automated version of text-section-literals: literal
pool candidate frags are planted every N frags and during relaxation
they are turned into actual literal pools where literals are moved to
become reachable for their first reference by L32R instruction.

This fixes a segfault when macro definitions end on the last line of a
file, and that line isn't properly terminated with a newline. gas
used to throw away the last line in cases like this, whereas in other

consistently provide a missing newline.

Back in the day support for these processors was added, we probably
didn't want to waste PPC_OPCODE bits on minor variations. I've had a
complaint that disassembly of mfspr/mtspr was wrong for power8. This
patch fixes that problem.
Note that since -m860/-m850/-m821 are new gas options enabling the
mpc8xx specific mfspr/mtspr variants it is possible that this change
will break some mpc8xx assembly code. ie. you might need to modify
makefiles to pass -m860 to gas.
