rustc: Start "stabilizing" some flags This commit shuffles around some CLI flags of the compiler to some more stable locations with some renamings. The changes made were: * The `-v` flag has been repurposes as the "verbose" flag. The version flag has been renamed to `-V`. * The `-h` screen has been split into two parts. Most top-level options (not all) show with `-h`, and the remaining options (generally obscure) can be shown with `--help -v` which is a "verbose help screen" * The `-V` flag (version flag now) has lost its argument as it is now requested with `rustc -vV` "verbose version". * The `--emit` option has had its `ir` and `bc` variants renamed to `llvm-ir` and `llvm-bc` to emphasize that they are LLVM's IR/bytecode. * The `--emit` option has grown a new variant, `dep-info`, which subsumes the `--dep-info` CLI argument. The `--dep-info` flag is now deprecated. * The `--parse-only`, `--no-trans`, and `--no-analysis` flags have moved behind the `-Z` family of flags. * The `--debuginfo` and `--opt-level` flags were moved behind the top-level `-C` flag. * The `--print-file-name` and `--print-crate-name` flags were moved behind one global `--print` flag which now accepts one of `crate-name`, `file-names`, or `sysroot`. This global `--print` flag is intended to serve as a mechanism for learning various metadata about the compiler itself. No warnings are currently enabled to allow tools like Cargo to have time to migrate to the new flags before spraying warnings to all users. 2014-12-15 18:03:39 -06:00			`LIB := $(shell $(RUSTC) --print file-names --crate-type=lib lib.rs)`

Redesign output flags for rustc This commit removes the -c, --emit-llvm, -s, --rlib, --dylib, --staticlib, --lib, and --bin flags from rustc, adding the following flags: * --emit=[asm,ir,bc,obj,link] * --crate-type=[dylib,rlib,staticlib,bin,lib] The -o option has also been redefined to be used for all flavors of outputs. This means that we no longer ignore it for libraries. The --out-dir remains the same as before. The new logic for files that rustc emits is as follows: 1. Output types are dictated by the --emit flag. The default value is --emit=link, and this option can be passed multiple times and have all options stacked on one another. 2. Crate types are dictated by the --crate-type flag and the #[crate_type] attribute. The flags can be passed many times and stack with the crate attribute. 3. If the -o flag is specified, and only one output type is specified, the output will be emitted at this location. If more than one output type is specified, then the filename of -o is ignored, and all output goes in the directory that -o specifies. The -o option always ignores the --out-dir option. 4. If the --out-dir flag is specified, all output goes in this directory. 5. If -o and --out-dir are both not present, all output goes in the current directory of the process. 6. When multiple output types are specified, the filestem of all output is the same as the name of the CrateId (derived from a crate attribute or from the filestem of the crate file).
