* config/tc-ppc.c (PPC_VLE_SPLIT16A): Delete unused macro.

	(PPC_VLE_SPLIT16D, PPC_VLE_LO16A, PPC_VLE_LO16D): Likewise.
	(PPC_VLE_HI16A, PPC_VLE_HI16D): Likewise.
	(PPC_VLE_HA16A, PPC_VLE_HA16D): Likewise.
	(md_apply_fix): Set fx_no_overflow for assorted relocations.
	Shift and sign-extend fieldval for use by some VLE reloc
	operand->insert functions.
