Create the typedesc type in one place. That is where it will be named.

04b239f3cb Use more precise spans in error messages for bad FRU exprs 
The type error message for an expression using FRU where a field
expression had the wrong type was using the span for the entire
expression. Fixed it to use the span for the individual field.

Closes #628.

f7a1006a07 Make resolve check for type-variable name-shadowing 
Capturing a type argument in the enclosing scope should be an error --
this commit implements that check in resolve, avoiding a potential
assertion failure in trans.

e1620def9f In typeck, check for dynamically sized by-value arguments to thunks 
A check in trans didn't have a corresponding check in typeck, causing
some programs (to wit, compile-fail/chan-parameterized-args.rs - part of this
commit) to fail with an assertion failure in trans instead of a type error.
Fixed it. In short, arguments that are future thunk arguments (any spawn
arguments, and _ arguments in bind) need to either not contain type params
or type vars, or be by-reference.

Closes #665.

did originally.
Also add more tests.

we try to construct derived tydescs from them.

86ee3454a1 Implement or-patterns in case clauses 
You can now say

    expr_move(?dst, ?src) | expr_assign(?dst, ?src) { ... }

to match both expr_move and expr_assign. The names, types, and number
of bound names have to match in all the patterns.

Closes #449.

4d325b1a15 Spill instead of copy when binding a pattern that's only a var binding 
The alias rules guarantee that the alt-ed value will outlive the binding's
last use, so this is safe.

This is a preparation for or-patterns. Joining scoped bindings seems like
it would get messy.

182c413af1 Propagate constraints through copy, move, and swap 
Assignments and moves with a simple local variable reference on the
RHS now propagate any typestate constraints the RHS was involved
in to the LHS. Swaps where both sides are local variables
exchange the constraints.

This was a pain in the butt and I'm still not proud of the resulting
code. Needs refactoring like whoa.

imported. This is more useful and avoids issue #482.
