[Bug rtl-optimization/80818] LRA clobbers live hard reg clobbered during rematerialization

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80818 --- Comment #2 from Andreas Krebbel --- I think this is a different problem. In my case the reason for adding an invalid rematerialization appears to be that the live ranges of an hard registers are not correctly calculated. I've just verified

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80725 --- Comment #3 from Andreas Krebbel --- process_address_1 does not do any address reloading because it only checks the first constraint letter whether it is an extra address constraint or not. In our case ("a,ZR") it is a register constraint.
