For non-Darwin platforms, we want to generate stack protectors only for
...
character arrays. This is in line with what GCC does.

the FailBB dominator is correctly calculated. Believe it or not, there isn't a

Don't try to add stack protector logic to a dead basic block. It messes up

In some cases, the "fail BB dominator" may be null after the BB was split (and
...
becomes reachable when before it wasn't). Check to make sure that it's not null
before trying to use it.

Fix the GCC test suite issue exposed by r127477, which was caused by stack
...
protector insertion not working correctly with unreachable code. Since that
revision was rolled out, this test doesn't actual fail before this fix.

Make more passes preserve dominators (or state that they preserve dominators if
...
they all ready do). This removes two dominator recomputations prior to isel,
which is a 1% improvement in total llc time for 403.gcc.
The only potentially suspect thing is making GCStrategy recompute dominators if
it used a custom lowering strategy.

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
...
must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize
the pass's dependencies.
Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.
I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems
with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass
registration/creation, please send the testcase to me directly.
