    Merge #1151 #1343
    
    1151: backend: handle deprecated attribute r=philberty a=liushuyu
    
    - handle the `deprecated` attribute
    
    1343: Ensure we support generic arguments on mangled type-paths r=philberty a=philberty
    
    This allows us to have the generic arguments within type paths for mangled
    symbols such as those in impl-blocks. This also updates our symbol
    managling to mangle comma's to $C$.
