9efdd0f326 Merge ast::proto_shared and ast::proto_closure
Now they are both just proto_shared and proto_shared takes an

f324704c0a Parse obj methods as proto_bare
I don't know if this is the right thing to do, but it works
and it lets 'fn' always mean proto_bare

070c39ca1d Split parsing of fn proto between types, items and anons

0714bb5f7d Fix the problem with check-fast randomly failing
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

8124846b2c Get rid of taskpointer-passing throughout the compiler
Only intrinsics still take a dummy taskptr. We'll have to do some
makefile stunts to snapshot a version without taskptrs-in-intrinsics.

e927df17f7 Remove spawn_wrap and main_wrap kludges
This isn't needed now that our functions are cdecl (and was apparently
only still working by accident).

314c011d71 Immutable and mutable? are covariant on their inner types
Whereas [mutable T] is invariant with respect to T, [T] and [mutable? T]
are covariant with respect to T.

d6613384fd Introduce covariance, contravariance and invariance to the type unifier
This will be used to resolve some problems with mutable? covariance and also
to implement function subtyping

b61578e1cd Don't unify from mutable? to immutable
Immutable is supposed to be a subtype of mutable-huh.

f7a825c614 Split record_var_binding into methods for expected and actual
This allows unify to maintain the same subtype relationship between
expected and actual throughout unify, which we are going to need
for mutable? and for function types.

007422cc04 Change the linkage order on linux and add -ldl
-lrt and -ldl need to be specified after -lrustrt since they are only used by
rustrt.

ad5014bf4c Fix link error by explicitly link needed DSOs
Building Rust(version 280bc56) on Ubuntu 11.10 failed with link error,
like:

compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/lib/libstd.so
compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/bin/rustc
/local/src/rust/build/stage0/lib/rustc/i686-unknown-linux-gnu/lib/librustrt.so:
undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
error: linking with gcc failed with code 1

GCC toolchain released by Ubuntu 11.10 introduced a few compiler flags
that are different with upstream GCC[1]. Flags "-Wl,--as-needed' and
'-Wl,--no-copy-dt-needed-entries' are passed by default.

Function clock_gettime from librt is used by librustrt, indirectly by
rustc. It is necessary to explicitly pass the "-lrt" flags when building
rustc.

Please note since the toolchain changes will be the default in the next
release(2.22) of binutils, this is not actually a Debian/Ubuntu specific
issue.

acf9b83e71 Fix a use of visit in rustc::middle::fn_usage
This was working by just skipping an AST node instead of doing the advertised
check. I can't find a test case for it, but this is more correct.

(fields don't work).

e8a0e592da reimplement some of the unsafe stuff which got lost
- blocks inherit unsafety
  - remove the --check-unsafe flag
  - add unsafe annotations where needed to get things to compile
