- split util_base.hpp from util.hpp - new namespaces: `mem` and `heap` - new `mem::Allocator` interface - new `heap::CAllocator` impl with global `heap::c_allocator` - new `heap::ArenaAllocator` impl - new `mem::TypeInfo` extracts names without RTTI - name extraction is enabled w/ ZIG_ENABLE_MEM_PROFILE=1 - new `mem::List` takes explicit `Allocator&` parameter - new `mem::HashMap` takes explicit `Allocator&` parameter - add Codegen.pass1_arena and use for all `ZigValue` allocs - deinit Codegen.pass1_arena early in `zig_llvm_emit_output()`
