cmd/compile: walk progs to generate debug_lines data Walking the progs is simpler than using the is_stmt symbol shenanigans. This is a reinstatement of CL 196661, which was rolled back due to tests failing. Unlike that original CL, this change should output the same debug_lines data the original approach wrote. The stats for JUST this CLC, note teh small speedup in compilation, and the lack of difference in binary size. name old time/op new time/op delta Template 229ms ± 4% 218ms ± 1% -4.95% (p=0.000 n=10+8)
