- <rdar://problem/16306600> QoI: passing a 'let' value as an inout results in an unfriendly diagnostic
- <rdar://problem/16927246> provide a fixit to change "let" to "var" if needing to mutate a variable
We now refer to an inout argument as such, e.g.:
t.swift:7:9: error: cannot pass 'let' value 'a' as inout argument
swap(&a, &b)
^
we also produce a note with a fixit to rewrite let->var in trivial cases where mutation is
being assed for, e.g.:
t.swift:3:3: note: change 'let' to 'var' to make it mutable
let a = 42
^~~
var
The note is produced by both Sema and DI.
