NVPTX: Remove the legacy ptx intrinsics

- Rename the ptx.read.* intrinsics to nvvm.read.ptx.sreg.* - some but
  not all of these registers were already accessible via the nvvm
  name.
- Rename ptx.bar.sync nvvm.bar.sync, to match nvvm.bar0.

There's a fair amount of code motion here, but it's all very
mechanical.

Init member structs in constructor.

Fixes build error on windows where MSVC does not
support list initialization inside member initializer list.

[NVPTX] Added NVVMIntrRange pass

NVVMIntrRange adds !range metadata to calls of NVVM intrinsics
that return values within known limited range.

This allows LLVM to generate optimal code for indexing arrays
based on tid/ctaid which is a frequently used pattern in CUDA code.
