Replace run-time on-demand initialisation of PL_bitcount with a constant table.
(The table is 256 bytes; the run-time initialisation code is larger than this!)
Adapt generate_uudmap.c to generate the initalisation block for PL_bitcount,
writing the code to bitcount.h, using the same approach as uudmap.h.
To preserve binary compatibility:
for MULTIPLICITY:
keep Ibitcount in the interpreter structure, but remove all the macros that
access it. PL_bitcount is a new symbol in the object file, which won't clash
with anything as that name wasn't used before.
otherwise:
keep PL_bitcount as a char *, but initialise it at compile time to a new
constant array PL_bitcount array. Remove the code that attempts to Safefree()
it at interpreter destruction time.
