[HIP] Fix unbundling HIP uses clang-offload-bundler to bundle intermediate files for host and different gpu archs together. When a file is unbundled, clang-offload-bundler should be called only once, and the objects for host and different gpu archs should be passed to the next jobs. This is because Driver maintains CachedResults which maps triple-arch string to output files for each job. This patch fixes a bug in Driver::BuildJobsForActionNoCache which uses incorrect key for CachedResults for HIP which causes clang-offload-bundler being called mutiple times and incorrect output files being used. It only affects HIP. Differential Revision: https://reviews.llvm.org/D47555 llvm-svn: 334128

[HIP] Do not unbundle object files for -fno-gpu-rdc When -fno-gpu-rdc is set, device code is compiled, linked, and assembled into fat binary and embedded as string in object files. The object files are normal object files which can be linked by host linker. In the linking stage, the object files should not be unbundled when -fno-gpu-rdc is set since they are normal object files, not bundles. The object files only need to be unbundled when -fgpu-rdc is set. Currently clang always unbundles object files, disregarding -fgpu-rdc option. This patch fixes that.

[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.
