2 simple changes,
1 - the gdb-invoked tests we're sometimes getting enough text that it
would interactively ask for
---Type <return> to continue, or q <return> to quit---
which would either cause a hang/timeout while it waited and/or failure.
Fixed by adding 'set height 0' in the script
2 - sync-mem-invalid.c still had tests for
__sync_mem_compare_exchange which no longer exists. so removed them
checked in as obvious.

* gcc.dg/sync-mem-invalid.c: Remove __sync_mem_compare_exchange test.
* gcc.dg/memmodel/memmodel.gdb: Avoid pagination.
