Reland "[clang][Driver] Support for the SPIR-V backend when compiling HIP" (llvm#169637)

mgcarrasco · 丹治秀樹 · commit 6b643f6a960f · 2025-11-27T11:16:18.000+09:00
This relands "[clang][Driver] Support for the SPIR-V backend when compiling HIP" llvm#167543. The only new change is a small fix for the multicall driver. For HIP, the SPIR-V backend can be optionally activated with the -use-spirv-backend flag. This option uses the SPIR-V BE instead of the SPIR-V translator. These changes also ensure that -use-spirv-backend does not require external dependencies, such as spirv-as and spirv-link
