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`.
With the recent fixes to method resolution, we can now remove the
dummy type parameters used as crutches in the iterator module.
For example, the zip adaptor type is just ZipIterator<T, U> now.
As the title says, valid debug info is now generated for any kind of pattern-based bindings like an example from the automated tests:
```rust
let ((u, v), ((w, (x, Struct { a: y, b: z})), Struct { a: ae, b: oe }), ue) =
((25, 26), ((27, (28, Struct { a: 29, b: 30})), Struct { a: 31, b: 32 }), 33);
```
(Not that you would necessarily want to do a thing like that :P )
Fixes#2533
Implements various missing tcp & udp methods.. Also fixes handling ipv4-mapped/compatible ipv6 addresses and addresses the XXX on `status_to_maybe_uv_error`.

This moves the raw struct layout of closures, vectors, boxes, and strings into a
new `unstable::raw` module. This is meant to be a centralized location to find
information for the layout of these values.
As safe method, `unwrap`, is provided to convert a rust value to its raw
representation. Unsafe methods to convert back are not provided because they are
rarely used and too numerous to write an implementation for each (not much of a
common pattern).
This is progress on #6790. I tried to get a nice interface for a trait to implement in the raw module, but I was unable to come up with one. The hard part is that there are so many different directions to go from one way to another that it's difficult to find a pattern to follow to implement a trait with. Someone else might have some better luck though.

Fix#8057
This commit fixes some oversights in the Makefile where rustc could be
invoked without some of its dependencies yet in place. (I encountered
the problem in practice; its not just theoretical.)
As written in Makefile.in, $(STAGE$(1)_T_$(2)_H_$(3)) is the way one
writes an invocation of rustc where $(1) is the stage number $(2) is
the target triple $(3) is the host triple. (Other uses of the macro
may plug in actual values or different parameters in for those three
formal parameters.)
When you have invocations of $(STAGE...), you need to make sure that
its dependences are satisfied; otherwise, if someone is using `make
-jN` for certain (large-ish) `N`, one can encounter situations where
GNU make attempts to invoke `rustc` before it has actually copied some
of its libraries into place, such as libmorestack.a, which causes a
link failure when the rustc invocation attempts to link in those
libraries.
In this case, the main prerequisite to add is TSREQ$(1)_T_$(2)_H_$(3),
which is described in Makefile.in as "Prerequisites for using the
stageN compiler to build target artifacts"
----
In addition to adding the extra dependences on TSREQ..., I also
replaced occurrences of the pattern:
TSREQ$(1)_T_$(2)_H_$(3)
$$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_STDLIB_$(2))
$$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_EXTRALIB_$(2))
with:
SREQ$(1)_T_$(2)_H_$(3)
which is equivalent to the above, as defined in Makefile.in
----
Finally, for the cases where TSREQ was missing in tests.mk, I went
ahead and put in a dependence on SREQ rather than just TSREQ, since it
was not clear to me how one could expect to compile those cases
without stdlib and extralib.
(It could well be that I should have gone ahead and done the same in
other cases where I saw TSREQ was missing, and put SREQ in those
cases as well. But this seemed like a good measure for now, without
needing to tax my understanding of the overall makefile
infrastructure much further.)
This moves the raw struct layout of closures, vectors, boxes, and strings into a
new `unstable::raw` module. This is meant to be a centralized location to find
information for the layout of these values.
As safe method, `repr`, is provided to convert a rust value to its raw
representation. Unsafe methods to convert back are not provided because they are
rarely used and too numerous to write an implementation for each (not much of a
common pattern).
The previous mode did a lot of very manual char-at-a-time parsing and was quite fragile and difficult to maintain. I talked to Marijn and he suggested I'd have better luck just rewriting it from scratch. This is the result of that effort; it seems to be faster, a bit easier on the eyes and more-or-less as well behaved when indenting. The algorithm is a bit different I suspect (it was hard to tell the previous one) but I tried to keep it simple and pleasant-looking.
