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 
The meaning of various fn incantations is going to get temporarily confusing

4341e50e3a Add safe versions of spawn using bare functions 
Currently they just wrap the unsafe versions. Will need to be rewritten
eventually.

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.

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.

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.

1a64153b24 Correct two more analyses of mutable? as mutable
