[CUDA] Disable PGO and coverage instrumentation in NVPTX. NVPTX does not have runtime support necessary for profiling to work and even call arc collection is prohibitively expensive. Furthermore, there's no easy way to collect the samples. NVPTX also does not support global constructors that clang generates if sample/arc collection is enabled.

[ADT] Normalize empty triple components LLVM triple normalization is handling "unknown" and empty components differently; for example given "x86_64-unknown-linux-gnu" and "x86_64-linux-gnu" which should be equivalent, triple normalization returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's config.sub returns "x86_64-unknown-linux-gnu" for both "x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the triple normalization to behave the same way, replacing empty triple components with "unknown". This addresses PR37129.
