    Merge #835
    
    835: Add name-resolution and HIR lowering pass for MatchExpr r=philberty a=philberty
    
    This adds the name-resolution and HIR lowering pass for the match-expr
    the type checking pass patch needs some work to be split up but these are
    two nice isolated commits which are easier to read.
