[Openmp-dev] Declare variant + Nvidia Device Offload

[Narayanaswamy, Ravi via Openmp-dev]

I was not following this thread.
Is this for function names only?
I believe if it is function names only should be ok.
Thanks
Ravi

I CC'ed Ravi and Jon to confirm that Intel and AMD toolchains will be
be fine with "$" in the symbol name. We already know it should work for
NVIDIA and NEC. I guess that would be all.

'$' works fine on amdgcn. We're using llvm-mc for the assembler and (nearly?) standard elf for the binary formats so it should work really. Hello world style test passes too.

Embedded \0 in the middle of the symbol name was rejected in IR but anything else seems to work.

Thanks!

Jon
