start moving `zig cc` to stage2 * build.zig: repair the ability to link against llvm, clang, and lld * move the zig cc arg parsing logic to stage2 - the preprocessor flag is still TODO - the clang arg iterator code is improved to use slices instead of raw pointers because it no longer has to deal with an extern struct. * clean up error printing with a `fatal` function and use log API for messages rather than std.debug.print * add support for more CLI options to stage2 & update usage text - hooking up most of these new options is TODO * clean up the way libc and libc++ are detected via command line options. target information is used to determine if any of the libc candidate names are chosen. * add native library directory detection * implement the ability to invoke clang from stage2 * introduce a build_options.have_llvm so we can comptime branch on whether LLVM is linked in or not.

simplify `zig info` and rename it to `zig env` also add version to it

delete all stage1 c++ code not directly related to compiling stage2 Deleted 16,000+ lines of c++ code, including: * an implementation of blake hashing * the cache hash system * compiler.cpp * all the linking code, and everything having to do with building glibc, musl, and mingw-w64 * much of the stage1 compiler internals got slimmed down since it now assumes it is always outputting an object file. More stuff: * stage1 is now built with a different strategy: we have a tiny zig0.cpp which is a slimmed down version of what stage1 main.cpp used to be. Its only purpose is to build stage2 zig code into an object file, which is then linked by the host build system (cmake) into stage1. zig0.cpp uses the same C API that stage2 now has access to, so that stage2 zig code can call into stage1 c++ code. - stage1.h is - stage2.h is - stage1.zig is the main entry point for the Zig/C++ hybrid compiler. It has the functions exported from Zig, called in C++, and bindings for the functions exported from C++, called from Zig. * removed the memory profiling instrumentation from stage1. Abandon ship! * Re-added the sections to the README about how to build stage2 and stage3. * stage2 now knows as a comptime boolean whether it is being compiled as part of stage1 or as stage2. - TODO use this flag to call into stage1 for compiling zig code. * introduce -fdll-export-fns and -fno-dll-export-fns and clarify its relationship to link_mode (static/dynamic) * implement depending on LLVM to detect native target cpu features when LLVM extensions are enabled and zig lacks CPU feature detection for that target architecture. * C importing is broken, will need some stage2 support to function again.

stage2: wire up -Dskip-non-native The purpose of this is to save time in the edit-compile-test cycle when working on stage2 code.
