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.

2928dbea72 Apparently MSVC doesn't support thread-safe static local initialization. Roll our own solution instead.

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.

a8a7bf484f Move the pass initialization helper functions into the llvm namespace, and add 
a header declaring them all.  This is also where we will declare per-library pass-set
initializer functions down the road.

123f4e5c19 Pass initialization functions should take a PassRegistry as a parameter 
rather than being fixed to the global registry.

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.

5f218b8612 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch 
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

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.
