Build instructions for old versions

hipSYCL 0.9.4

Clang 17

Building hipSYCL v0.9.4 with mainline Clang 17.0.2 fails with the following errors:

fatal error: llvm/Analysis/SyncDependenceAnalysis.h: No such file or directory

Older versions of Clang (e.g., hipSYCL 0.9.4 + Clang 15) or newer versions of AdaptiveCpp (e.g., AdaptiveCpp 23.10.0-alpha + Clang 17) work fine.

Suggested workaround

• Remove #include "llvm/Transforms/IPO/PassManagerBuilder.h" from include/hipSYCL/compiler/GlobalsPruningPass.hpp (sed '/PassManagerBuilder\.h/d' -i include/hipSYCL/compiler/GlobalsPruningPass.hpp), and
• Disable CPU acceleration (cmake -DWITH_ACCELERATED_CPU=OFF).
