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

451a0accb5 add uadd_ov/usub_ov to apint, consolidate constant folding 
logic to use the new APInt methods.  Among other things this
implements rdar://8501501 - llvm.smul.with.overflow.i32 should constant fold

which comes from "clang -ftrapv", originally brought to my attention from PR8221.

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.

c9709f154d Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

e9771f15f7 Now using a variant of the existing inlining heuristics to decide whether to create a given specialization of a function in PartialSpecialization. If the total performance bonus across all callsites passing the same constant exceeds the specialization cost, we create the specialization.

0545afa8fd Start separating out code metrics into code size metrics and code performance metrics. Partial Specialization will apply the former to function specializations, and the latter to all callsites that can use a specialization, in order to decide whether to create a specialization

1d81101e97 After splitting, the remaining LiveInterval may be fragmented into multiple 
connected components. These components should be allocated different virtual
registers because there is no reason for them to be allocated together.

Add the ConnectedVNInfoEqClasses class to calculate the connected components,
and move values to new LiveIntervals.

Use it from SplitKit::rewrite by creating new virtual registers for the
components.
