+Backport fix for PR target/58595

+Subject: [PATCH]        PR target/58595         * config/arm/arm.c
+ (arm_tls_symbol_p): Remove.    (arm_legitimize_address): Call
+ legitimize_tls_address for any         arm_tls_referenced_p expression,
+ handle constant addend.  Call it       before testing for !TARGET_ARM. 
+ (thumb_legitimize_address): Don't handle arm_tls_symbol_p here.
+
+        * gcc.dg/tls/pr58595.c: New test.
