Erroneous ambiguous method error

[nikomatsakis]

Trying to use position() method on vecs, I get errors like

/Users/nmatsakis/versioned/rust-green/src/rustc/middle/typeck/check/method.rs:364:18: 364:44 error: multiple applicable methods in scope

that seem erroneous. Left some FIXMEs for uglier code that resulted from having to call vec::position() explicitly.

I think this is fixed. Testing.

Can close this when #5065 lands.
