  Log Message:
  -----------
  Expand the fp_to_int/int_to_fp/fp_round/fp_extend as libcall for fp128

X86 and AArch64 expand it as libcall inside the target. And PowerPC also
want to expand them as libcall for P8. So, propose an implement in the
legalizer to common the logic and remove the code for X86/AArch64 to
avoid the duplicate code.
