From: Romain Naour <romain.naour@smile.fr>

This target version is needed for Rusticl which is an LLVM based OpenCL
framework[1]. Rusticl allow programs to compile OpenCL C/C++ code
at runtime with Clang. Clang generates LLVM IR which is translated into
SPIR-V by spirv-llvm-translator. Finally, mesa can use its internal
tools to manage SPIR-V.
