* add TypedValue.Managed which represents a Type, a Value, and some kind of memory management strategy. * introduce an analysis queue * flesh out how incremental compilation works with respect to exports * ir.text.Module is only capable of one error message during parsing * link.zig no longer has a decl table map and instead has structs that exist directly on ir.Module.Decl and ir.Module.Export * implement primitive .text block allocation * implement linker code for updating Decls and Exports * implement null Type Some supporting std lib changes: * add std.ArrayList.appendSliceAssumeCapacity * add std.fs.File.copyRange and copyRangeAll * fix std.HashMap having modification safety on in ReleaseSmall builds * add std.HashMap.putAssumeCapacityNoClobber
