Combine a bunch of small files into a single, still rather small, file. The primary purpose of this is to get all of the static initializers into a single file so as to have a well defined order of initialization.

This change reverts the interesting parts of 226311 (and 227046). This change introduced two problems, and I've been convinced that an alternate approach is preferrable anyways.
The bugs were:
- Registery appears to require all users be within the same linkage unit. After this change, asking for "statepoint-example" in Transform/ would sometimes get you nullptr, whereas asking the same question in CodeGen would return the right GCStrategy. The correct long term fix is to get rid of the utter hack which is Registry, but I don't have time for that right now. 227046 appears to have been an attempt to fix this, but I don't believe it does so completely.
- GCMetadataPrinter::finishAssembly was being called more than once per GCStrategy. Each Strategy was being added to the GCModuleInfo multiple times.
Once I get time again, I'm going to split GCModuleInfo into the gc.root specific part and a GCStrategy owning Analysis pass. I'm probably also going to kill off the Registry. Once that's done, I'll move the new GCStrategyAnalysis and all built in GCStrategies into Analysis. (As original suggested by Chandler.) This will accomplish my original goal of being able to access GCStrategy from Transform/ without adding all of the builtin GCs to IR/.

Note: This change ended up being slightly more controversial than expected. Chandler has tentatively okayed this for the moment, but I may be revisiting this in the near future after we settle some high level questions.
Rather than have the GCStrategy object owned by the GCModuleInfo - which is an immutable analysis pass used mainly by gc.root - have it be owned by the LLVMContext. This simplifies the ownership logic (i.e. can you have two instances of the same strategy at once?), but more importantly, allows us to access the GCStrategy in the middle end optimizer. To this end, I add an accessor through Function which becomes the canonical way to get at a GCStrategy instance.
In the near future, this will allows me to move some of the checks from http://reviews.llvm.org/D6808 into the Verifier itself, and to introduce optimization legality predicates for some of the recent additions to InstCombine. (These will follow as separate changes.)

VISIBILITY_HIDDEN removal.

Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

Split Support/Registry.h into two files so that we have less to
recompile every time CommandLine.h is changed.

In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:
Collector -> GCStrategy
CollectorMetadata -> GCFunctionInfo
CollectorModuleMetadata -> GCModuleInfo
CollectorRegistry -> GCRegistry
Function::getCollector -> getGC (setGC, hasGC, clearGC)
Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.
