Björn Steinbrink 00ba8b3ac0 Improve handling of immediate return values
We currently still handle immediate return values a lot like
non-immediate ones. We provide a slot for them and store them into
memory, often just to immediately load them again. To improve this
situation, trans_call_inner has to return a Result which contains the
immediate return value.

Also, it also needs to accept "No destination" in addition to just
SaveIn and Ignore. Since "No destination" isn't something that fits
well into the Dest type, I've chosen to simply use Option<Dest>
instead, paired with an assertion that checks that "None" is only
allowed for immediate return values.

This is a preliminary version of the Rust compiler, libraries and tools

Source layout:

librustc/          The self-hosted compiler

libstd/            The standard library (imported and linked by default)
libextra/          The "extras" library (slightly more peripheral code)
libsyntax/         The Rust parser and pretty-printer

rt/                The runtime system
rt/rust_*.cpp      - The majority of the runtime services
rt/isaac           - The PRNG used for pseudo-random choices in the runtime
rt/bigint          - The bigint library used for the 'big' type
rt/uthash          - Small hashtable-and-list library for C, used in runtime
rt/sync            - Concurrency utils
rt/util            - Small utility classes for the runtime.
rt/vg              - Valgrind headers
rt/msvc            - MSVC support
rt/linenoise       - a readline-like line editing library

test/              Testsuite
test/compile-fail  - Tests that should fail to compile
test/run-fail      - Tests that should compile, run and fail
test/run-pass      - Tests that should compile, run and succeed
test/bench         - Benchmarks and miscellanea
test/pretty        - Pretty-printer tests
test/auxiliary     - Dependencies of tests

compiletest/       The test runner

librustpkg/        The package manager and build system

librusti/          The JIT REPL

librustdoc/        The Rust API documentation tool

llvm/              The LLVM submodule

libuv/             The libuv submodule

rustllvm/          LLVM support code

libfuzzer/         A collection of fuzz testers

etc/               Scripts, editor support, misc
