pa.md: Split tgd_load, tld_load and tie_load into pic and non-pic versions. 

* config/pa/pa.md: Split tgd_load, tld_load and tie_load
	into pic and non-pic versions. Mark r19 as used for 
	tgd_load_pic, tld_load_pic and tie_load_pic. Mark r27 as used 
	for tgd_load, tld_load and tie_load .
	* config/pa/pa.c (legitimize_tls_address): Emit pic or non-pic
	version of tgd_load, tld_load and tie_load depending on the 
	value of flag_pic.
