Joel E. Denny 9fa9c9368d [FileCheck] Add -allow-deprecated-dag-overlap to failing llvm tests
See https://reviews.llvm.org/D47106 for details.

This commit drops that patch's changes to:

  llvm/test/CodeGen/NVPTX/f16x2-instructions.ll
  llvm/test/CodeGen/NVPTX/param-load-store.ll

For some reason, the dos line endings there prevent me from commiting
via the monorepo.  A follow-up commit (not via the monorepo) will
finish the patch.

David Majnemer 5fa7d48bb8 [NVVMIntrRange] Only set range metadata if none is already present
The range metadata inserted by NVVMIntrRange is pessimistic, range
metadata already present could be more precise.

Justin Bogner a466cc33fa 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.

Artem Belevich 49e9a81236 [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.

Justin Holewinski 3e037d98e6 [NVPTX] Rename registers %fl -> %fd and %rl -> %rd
This matches the internal behavior of NVIDIA tools like libnvvm.

Justin Holewinski dbb3b2f4b6 [NVPTX] Re-enable support for virtual registers in the final output
Now that 3.3 is branched, we are re-enabling virtual registers to help
iron out bugs before the next release. Some of the post-RA passes do
not play well with virtual registers, so we disable them for now. The
needed functionality of the PrologEpilogInserter pass is copied to a
new backend-specific NVPTXPrologEpilog pass.

The test for this commit is not breaking the existing tests.

Justin Holewinski ae556d3ef7 This patch adds a new NVPTX back-end to LLVM which supports code generation for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it.
The new target machines are:

nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX

The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.
