RFA: remove tm.h include from function.h


This patch removes the tm.h include from function.h
The target dependent stuff from x_rtl is moved to the new struct variable x_tm_rtl.
Some files have been exposed clandestinely using tm.h without including it
directly.
I generate a new header file, tm-holdover.h, for BITS_PER_UNIT.
This can be used instead of tm.h if all other macros from tm.h are gone
in a source file.


With the patches for PR46500 and PR46623,
bootstrapped on i686-pc-linux-gnu, and cross-tested for:
alpha-linux-gnu hppa-linux-gnu mips-elf sh-elf arc-elf ia64-elf mmix-knuth-mmixware sparc-elf arm-eabi iq2000-elf mn10300-elf spu-elf avr-elf lm32-elf moxie-elf v850-elf bfin-elf m32c-elf pdp11-aout vax-linux-gnu cris-elf m32r-elf picochip-elf xstormy16-elf crx-elf m68hc11-elf ppc-elf xtensa-elf fr30-elf m68k-elf rx-elf frv-elf mcore-elf s390-linux-gnu h8300-elf mep-elf score-elf microblaze-elf ,


then back-ported to current trunk and re-bootstrapped & regtested
for i686-pc-linux-gnu.
