[committed] Use target-insns.def for reload_load_address

[Richard Sandiford]

Bootstrapped & regression-tested on x86_64-linux-gnu and aarch64-linux-gnu.
Also tested via config-list.mk.  Committed as preapproved.

Thanks,
Richard


gcc/
	* target-insns.def (reload_load_address): New targetm instruction
	pattern.
	* reload1.c (gen_reload): Use it instead of HAVE_*/gen_* interface.
