    Merge #1632
    
    1632: Fix mac-os regression in apply generic arguments to method calls r=philberty a=philberty
    
    When applying generic arguments to method calls such as:
    
    ```receiver.method_name<i32, bool>()```
    
    This ended up wrongly using the default constructor with an empty generic arguments which seems
    like a possible bug in the new version of clang. This explicitly sets up all relevant copy constructors
    for HIR::PathExprSegment and removes the defaults.
