The current diagnostic functions log/warn/error/fatal lack a context argument and call the global `lld::errorHandler()`, which prevents multiple lld instances in one process. This patch introduces context-aware replacements: * log => Log(ctx) * warn => Warn(ctx) * errorOrWarn => Err(ctx) * error => ErrAlways(ctx) * fatal => Fatal(ctx) Example: `errorOrWarn(toString(f) + "xxx")` => `Err(ctx) << f << "xxx"`. (`toString(f)` is shortened to `f` as a bonus and may access `ctx` without accessing the global variable (see `Target.cpp`)). `ctx.e = &context->e;` can be replaced with a non-global Errorhandler when `ctx` becomes a local variable. (For the ELF port, the long term goal is to eliminate `error`. Most can be straightforwardly converted to `Err(ctx)`.)
