powerpc/Asm: simplify the modeling of Csymbol_low and Csymbol_high.
powerpc/Asmgen*: simplify the code generated for far-data relative
accesses, so that the only occurrences of Csymbol_rel_{low,high}
are in the pattern
Paddis(r, GPR0, Csymbol_rel_high...); Paddi(r, r, Csymbol_rel_low...)
checklink/Check.ml: check the pattern above.
