rtl-optimization: [PR102733] DSE removing address which only differ by address space.
The problem here is DSE was not taking into account the address space
which meant if you had two addresses say `fs:0` and `gs:0` (on x86_64),
DSE would think they were the same and remove the first store.
This fixes that issue by adding a check for the address space too.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR rtl-optimization/102733
gcc/ChangeLog:
* dse.cc (store_info): Add addrspace field.
(record_store): Record the address space
and check to make sure they are the same.
gcc/testsuite/ChangeLog:
* gcc.target/i386/addr-space-6.c: New test.
