[COMMITTED] hppa: Use optab_libfunc to access sync_lock_test_and_set libfunc

[John David Anglin]

This patch revises the atomic store code for hppa-linux to use optab_libfunc
to access the sync_lock_test_and_set libfunc. We now call
convert_memory_address() to convert the memory address to Pmode. This
should handle more memory addresses.

Tested on hppa-unknown-linux-gnu. Committed to trunk and gcc-11 branch.

Use optab_libfunc to access sync_lock_test_and_set libfunc on hppa-linux.

gcc/ChangeLog:

        * config/pa/pa.md (atomic_storeq): Use optab_libfunc to access
        sync_lock_test_and_set libfunc. Call convert_memory_address to
        convert memory address to Pmode.
        (atomic_storehi, atomic_storesi, atomic_storedi): Likewise.
