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).

Issue #992

243c5c3479 Use snap runtime, and the old main.o, for stage1 
This is intended to be reverted again after I register the next
snapshot.

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.
