fc10724777 Add Tsan annotations to the pass system. 
Perhaps once(&func) should be hoisted into lib/Support.

17ae92b2d8 Add support for plugins add passes to the default set of passes. The standard set of passes used by front ends can now be modified by LLVM plugins, without needing to modify any front ends. 
Still to do:

- Allow replacing / removing passes (infrastructure there, just needs an infrastructure exposed)
- Defining sets of passes to be added or removed as a group
- Extending the support to allow user-defined groups of optimisations
- Allow plugins to be specified for loading automatically (e.g. from plugins.conf or some similar mechanism)

46990c17f7 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.

467d56737b Try again at implementing thread-safe lazy pass initialization, without depending on static local initialization 
being threadsafe AND ensuring that initialization is complete by the time the initializeFooPass method returns.

2ea9b016d8 Conversely, Analysis-implementations do NOT need to initialize the AnalysisGroup. It will only matter when 
someone tries to require that AG, in which case it is the requester's responsibility to initialize it.

63f757463c Begin adding static dependence information to passes, which will allow us to 
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

38e84dd7ea Another step towards getting rid of static ctors for pass registration: have INITIALIZE_PASS AND INITIALIZE_AG_PASS 
expand to an initializeMyPass() function (in additional to the extant static ctors).  Eventually, these will be called
from a big InitializeAllPasses() function, and the PassInfo's they create (which would be leaked if this code were used
at the moment) will be handed off to a PassRegistry for ownership.

522ef60c01 Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented 
linked list.  This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

138a53b303 Change class' public PassInfo variables to by initialized with the 
address of the PassInfo directly instead of calling getPassInfo.
This eliminates a bunch of dynamic initializations of static data.

Also, fold RegisterPassBase into PassInfo, make a bunch of its
data members const, and rearrange some code to initialize data
members in constructors instead of using setter member functions.
