r? @graydon Package IDs can now be of the form a/b/c#FOO, where (if a/b/c is
a git repository) FOO is any tag in the repository. Non-numeric
tags only match against package IDs with the same tag, and aren't
compared linearly like numeric versions.
While I was at it, refactored the code that calls `git clone`, and segregated build output properly for different packages.
With an expression like
static w : foo = foo { a:5, ..x };
Rust currently gives the error "constant contains unimplemented expression type". This branch implements support for constant structs with `..base`.
This fixes the recently introduced peak memory usage regression by
freeing the intermediate results as soon as they're not required
anymore instead of keeping them around for the whole compilation
process.

Adds a fence operation to close#8061
Also adds static initializers to for atomic types. Since the fields are private, you aren't able to have `static mut` variables that are an atomic type. Each atomic type's initializer starts at a 0-value (so unset for `AtomicFlag` and false for `AtomicBool`).
#7617
While the code that was there should've been perfectly fine (and seemingly is on linux at least) there seems to be some sort of weird interaction going on with statics and vectors. I couldn't get a smaller test case to reproduce that behaviour. The for loop in `rust::usage` seemingly just goes past the end of the vector thus getting garbage which it tries to pass to malloc somewhere down the line.
In any case, using a fixed length vector seems to mitigate this.
Good evening,
This is a superset of @MaikKlein's #7969 commit, that I've fixed up to compile. I had a couple commits I wanted to do on top of @MaikKlein's work that I didn't want to bitrot.
To be more specific:
`UPPERCASETYPE` was changed to `UppercaseType`
`type_new` was changed to `Type::new`
`type_function(value)` was changed to `value.method()`

The purpose here is to get rid of compile_upto, which pretty much always requires the user to read the source to figure out what it does. It's replaced by a sequence of obviously-named functions:
- phase_1_parse_input(sess, cfg, input);
- phase_2_configure_and_expand(sess, cfg, crate);
- phase_3_run_analysis_passes(sess, expanded_crate);
- phase_4_translate_to_llvm(sess, expanded_crate, &analysis, outputs);
- phase_5_run_llvm_passes(sess, &trans, outputs);
- phase_6_link_output(sess, &trans, outputs);
Each of which takes what it takes and returns what it returns, with as little variation as possible in behaviour: no "pairs of options" and "pairs of control flags". You can tell if you missed a phase because you will be missing a `phase_N` call to some `N` between 1 and 6.
It does mean that people invoking librustc from outside need to write more function calls. The benefit is that they can _figure out what they're doing_ much more easily, and stop at any point, rather than further overloading the tangled logic of `compile_upto`.
