rustc default compiler optimization level is O3. This change removes the option that overrides the default optimization level, because it is safe to do so. The code generation is incorrect in some cases because of link-time optimizations, which remain disabled for compiling BPF programs. In addition, this commit updates the expected instruction counts for assert_instruction_count test.
