arm: cleanup legacy ARM_PE code

The arm 'pe' target was removed back in 2012 when the FPA support was
removed, but in a small number of places some conditional code was
accidentally left behind.  It's no-longer needed, so remove it.

gcc/ChangeLog:

	* config/arm/arm-protos.h (arm_dllexport_name_p): Remove prototype.
	(arm_dllimport_name_p): Likewise.
	(arm_pe_unique_section): Likewise.
	(arm_pe_encode_section_info): Likewise.
	(arm_dllexport_p): Likewise.
	(arm_dllimport_p): Likewise.
	(arm_mark_dllexport): Likewise.
	(arm_mark_dllimport): Likewise.
	(arm_change_mode_p): Likewise.
	* config/arm/arm.cc (arm_gnu_attributes): Remove attributes for ARM_PE.
	(TARGET_ENCODE_SECTION_INFO): Remove setting for ARM_PE.
	(is_called_in_ARM_mode): Remove ARM_PE conditional code.
	(thumb1_output_interwork): Remove obsolete ARM_PE code.
	(arm_encode_section_info): Remove surrounding #ifndef.
