This patch switches eh data to always use pc relative/indirect
encoding, to avoid relocations of unaligned words.  Backported to 4.7
and 4.8.

	* config/tilegx/tilegx.c (tilegx_asm_preferred_eh_data_format):
	Use indirect/pcrel encoding.
	* config/tilepro/tilepro.c (tilepro_asm_preferred_eh_data_format):
	Ditto.
