Since we are now using intrusive ref counts, we can easily turn any
pointer to a module into a shared pointer just by assigning it.

We had some cases where getting the shared pointer for a module from
the global module list was causing a performance issue when debugging
with DWARF in .o files. Now that the module uses intrusive ref counts,
we can easily convert any pointer to a shared pointer.

header file information we already have. Otherwise, we might forget
something we already knew (e.g., that the header was #import'd already).

As per discussion with Doug Gregor on the IRC channel, introduce a new compiler switch: -fms-compatility. 

Microsoft specific tweaking will now fall into 2 categories:

    - fms-extension: Microsoft specific extensions that should never change the meaning of an otherwise well formed code. Currently map to LangOptions::Microsoft. (To be clearer, I am planning to change the name to LangOptions::MicrosoftExt).

    - fms-compatibility: Really a MSVC emulation mode. Map to LangOptions::MicrosoftMode. Can change the meaning of an otherwise standard conformant program.

arbitrary amount of code. This forces us to stage the AST writer more
strictly, ensuring that we don't assign a declaration ID to a
declaration until after we're certain that no more modules will get
loaded.

Fix massive LiveVariables regression (due to LiveVariables rewrite) by addressing two performance problems:

- Speed of "merge()", which merged data flow facts.  This was doing a set canonicalization on every insertion, which was super slow.
  To fix this, we use ImmutableSetRef.

- Visit CFGBlocks in reverse postorder.  This is a huge speedup, as on some test cases the algorithm would take many iterations
  to converge.

This contains a bunch of copy-paste from UninitializedValues.cpp and ThreadSafety.cpp.  The idea
was to get something working first, and then refactor the common logic for all three files into
a separate analysis/library entry point.

Add ImmutableMapRef and ImmutableSetRef, which consolidate Immutable[Map,Set] and its Factory.  This may eventually replace Immtuable[Map,Set].

afterwards.
