Rework workaround for GCC regarding -fno-lifetime-dse #20304
Description
Describe the bug
llvm/llvm-project#24952 is causing failures in sycl-ls,
so we have to revert 6ac6312 and apply workarounds in e676cb0.
bader left a comment (intel/llvm#20292)
I suggest we recover 6ac6312 and implement a workaround for sycl-ls, rather than add more changes in the community code to recover from previous community code modifications.
To reproduce
revert e676cb0 and reland 6ac6312
run sycl-ls, you should see SEGV.
Environment
- OS: [e.g Windows/Linux]
- Target device and vendor: [e.g. Intel GPU]
- DPC++ version: [e.g. commit hash or output of
clang++ --version] - Dependencies version: [e.g. the output of
sycl-ls --verbose]
