Relands #206910 (reverted in #213088) with the fix for the breakage. IsIntegratedBackendDefault() was tied to whether the SPIR-V backend is registered, but it also controls whether clang collapses the compile and backend jobs, so builds without the SPIR-V target split every HIPSPV RDC device compile and failed hipspv-toolchain-rdc.hip. The default is back to the base class value and the translator fallback is decided in constructLinkAndEmitSpirvCommand. Third commit adds a test not guarded by spirv-registered-target. Validated in X86;SPIRV and X86 only builds: driver tests pass in both, and non-RDC plus RDC (new driver) flows run for real emit spirv-val clean modules via the backend and via llvm-spirv respectively.

// Coverage for HIPSPV behavior that must not depend on whether the in-tree

// SPIR-V backend was built. Deliberately not guarded by the
