Emit source locations manually for more precise tracking. Don't infer them from emitted bytecode opcodes because that leads to inaccurate and sometimes surprising results. Speeds up code generation (although infinitesimally) as a bonus. Fixes: quickjs-ng#236

Fixes: #236
I initially planned to open this as a draft but in my (admittedly light) testing it works remarkably well. We now emit the exact same stack trace for the test case from #236.
