Pull GetSoftwareBreakpointPCOffset into base class

Summary:
This function encodes the knowledge of whether the PC points to the
breakpoint instruction of the one following it after the breakpoint is
"hit". This behavior mainly(*) depends on the architecture and not on the
OS, so it makes sense for it to be implemented in the base class, where
it can be shared between different implementations (Linux and NetBSD
atm).

(*) It is possible for an OS to expose a different API, perhaps by doing
some fixups in the kernel. In this case, the implementation can override
this function to implement custom behavior.

[X86] Disable BMI BEXTR in X86DAGToDAGISel::matchBEXTRFromAnd unless we're on compiling for a CPU with single uop BEXTR

Summary:
This function turns (X >> C1) & C2 into a BMI BEXTR or TBM BEXTRI instruction. For BMI BEXTR we have to materialize an immediate into a register to feed to the BEXTR instruction.

The BMI BEXTR instruction is 2 uops on Intel CPUs. It looks like on SKL its one port 0/6 uop and one port 1/5 uop. Despite what Agner's tables say. I know one of the uops is a regular shift uop so it would have to go through the port 0/6 shifter unit. So that's the same or worse execution wise than the shift+and which is one 0/6 uop and one 0/1/5/6 uop. The move immediate into register is an additional 0/1/5/6 uop.

For now I've limited this transform to AMD CPUs which have a single uop BEXTR. If may also might make sense if we can fold a load or if the and immediate is larger than 32-bits and can't be encoded as a sign extended 32-bit value or if LICM or CSE can hoist the move immediate and share it. But we'd need to look more carefully at that. In the regression I looked at it doesn't look load folding or large immediates were occurring so the regression isn't caused by the loss of those. So we could try to be smarter here if we find a compelling case.

Add support for encoding type arguments for lightweight generics in

This should complete the coverage of the ObjC extensions that clang currently
supports under the MS style name decoration scheme.

This is implemented similar to the Objective-C lifetime qualifiers decoration:
a template specialization in the `__ObjC` namespace so that we can interoperate
with Microsoft's tools as well as ensure that we do not accidentally collide
with new features in the Microsoft implementation.

Since the `__kindof` appertains to the type and not the pointer, we apply the
template specialization to the underlying type instead of the pointer type.

Unfortunately, until D52581 is resolved, the generated name is not really
compatible with the MS tools as well as breaks interoperability with
Objective-C++ and C++.

The target check-libomptarget-nvptx is not run by default because
 - we can't determine if there is a GPU plugged into the system.
 - it will require the latest Clang compiler. Keeping compatibility

passes but takes more than 3 minutes to do so. I could increase the
