util/cacheflush.c: Update cache flushing mechanism for Emscripten
Although __builtin___clear_cache is used to flush the instruction cache for a specified memory region, this operation doesn't apply to wasm, as its memory isn't executable. Moreover, Emscripten does not support this builtin and fails to compile it with the following error. > fatal error: error in backend: llvm.clear_cache is not supported on wasm To resolve this, this commit removes the call to __builtin___clear_cache for Emscripten build.
