    Merge #738
    
    738: Refactor HIR to use new Mutability enum r=philberty a=dafaust
    
    Introduce a new header rust/util/rust-common.h and move the enum
    previously Rust::TyTy::TypeMutability there as Rust::Mutability.
    
    Update the following objects to use Mutability enum rather than a bool:
    - HIR::IdentifierPattern
    - HIR::ReferencePattern
    - HIR::StructPatternFieldIdent
    - HIR::BorrowExpr
    - HIR::RawPointerType
    - HIR::ReferenceType
    - HIR::StaticItem
    - HIR::ExternalStaticItem
    
    Also add a HIR::SelfParam::get_mut () helper, mapping its internal
    custom mutability to the common Rust::Mutability.
    
    Fixes: #731
