[RS6000] Use LIB2_SIDITI_CONV_FUNCS in place of ppc64-fp.c
This patch retires ppc64-fp.c in favour of using "LIB2_SIDITI_CONV_FUNCS = yes", which is a lot better solution than having a copy of selected libgcc2.c functions. * config/rs6000/t-ppc64-fp (LIB2ADD): Delete. (LIB2_SIDITI_CONV_FUNCS): Define. * config/rs6000/ppc64-fp.c: Delete file.
