Having RHSKnownZero and RHSKnownOne be alternative names for KnownZero and KnownOne
(via APInt &RHSKnownZero = KnownZero, etc) seems dangerous and confusing to me: it
is easy not to notice this, and then wonder why KnownZero/RHSKnownZero changed
underneath you when you modified RHSKnownZero/KnownZero etc. So get rid of this.

Kill ModuleProvider and ghost linkage by inverting the relationship between
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.
Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods. The bindings to
other languages still use the ModuleProvider concept. It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fix inline cost predictions with SCIENCE.
After running a batch of measurements, it is clear that the inliner metrics
need some adjustments:
Own argument bonus: 20 -> 5
Outgoing argument penalty: 0 -> 5
Alloca bonus: 10 -> 5
Constant instr bonus: 7 -> 5
Dead successor bonus: 40 -> 5*(avg instrs/block)
The new cost metrics are generaly 25 points higher than before, so we may need
to move thresholds.
With this change, InlineConstants::CallPenalty becomes a political correction:
if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction()))
NumInsts += InlineConstants::CallPenalty + CS.arg_size();
The code size is accurately modelled by CS.arg_size(). CallPenalty is added
because calls tend to take a long time, so it may not be worth it to inline a
function with lots of calls.
All of the political corrections are in the InlineConstants namespace:
IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty,
NoreturnPenalty.
