	* arm-reloc-property.cc
	(Arm_reloc_property_table::reloc_name_in_error_message): New method
	definition.
	* arm-reloc-property.h
	(Arm_reloc_property_table::get_implemented_static_reloc_property):
	New method definition.
	(Arm_reloc_property_table::reloc_name_in_error_message): New method
	declaration.
	* arm-reloc.def (THM_MOVT_ABS, THM_MOVT_PREL, THM_MOVT_BREL): Change
	overflow to N.
	(GOT_PREL): Change implemented to Y.
	* arm.cc (Target_arm::reloc_uses_thumb_bit): Remove method.
	(Target_arm::Relocate::reloc_needs_sym_origin): Remove method.
	(Arm_relocate_functions::movw_abs_nc): Remove method.
	(Arm_relocate_functions::movt_abs): Ditto.
	(Arm_relocate_functions::thm_movw_abs_nc): Ditto.
	(Arm_relocate_functions::thm_movt_abs): Ditto.
	(Arm_relocate_functions::movw_rel_nc): Ditto.
	(Arm_relocate_functions::movw_rel): Ditto.
	(Arm_relocate_functions::movt_rel): Ditto.
	(Arm_relocate_functions:thm_movw_rel_nc): Ditto.
	(Arm_relocate_functions:thm_movw_rel): Ditto.
	(Arm_relocate_functions:thm_movt_rel): Ditto.
	(Arm_relocate_functions::movw, Arm_relocate_functions::movt,
	(Arm_relocate_functions::thm_movw, Arm_relocate_functions::thm_movt):
	New method definitions.
	(Arm_relocation_functions::arm_grp_alu): Add assertion for group index.
	(Arm_relocation_functions::arm_grp_ldr): Ditto.
	(Arm_relocation_functions::arm_grp_ldrs): Ditto.
	(Arm_relocation_functions::arm_grp_ldc): Ditto.
	(Target_arm::Relocate::relocate): Check for non-static or
	unimplemented relocation code and exit early.  Change calls to
	Target_arm::reloc_uses_thumb_bit and
	Target_arm::Reloc::reloc_needs_sym_origin to use relocation property
	instead.  Refactor code to handle similar relocations to increase
	code sharing.  Remove check for unsupported relocation code in switch
	statement.
	(Target_arm::Relocatable_size_for_reloc::get_size_for_reloc): Use
	relocation property table to find out size.  Change error message to
	print out the name of a relocation code instead of the numeric value.
	(Target_arm::scan_reloc_for_stub): Use relocation property table
	instead of calling Target_arm::reloc_uses_thumb_bit().
