The following patch adds the --param(eters) needed to tweak the
optimizers into allowing or disallowing data races in cross-thread
visible data.
There will be additional flags added later to make these parameters
available to the common user. It has been suggested to use
-fmemory-model=xxx, but I will implement this later.
The next step will be to find out where we introduce the data races in
the testsuite, and fix the optimizers accordingly.
Committed to branch.
