reload reg.
From-SVN: r22571
* reload1.c (reload_cse_regs_1): Renamed from reload_cse_regs.
(reload_cse_regs): New function body: call reload_cse_regs_1,

reloads to RELOAD_FOR_X_ADDRESS reloads, test for reload sharing.

If there is not more than one RELOAD_FOR_X_ADDRESS, don't change
RELOAD_FOR_X_ADDR_ADDR reload.
