d: Merge upstream dmd 76e3b41375, druntime 1462ebd1, phobos 5fef0d28f.

Updates D language version to v2.100.1.

D front-end changes:

    - Fix delegate literal with inferred return value that requires
      following alias-this to not use class cast.
    - Fix internal error on variadic template type instantiated with two
      arrays of classes.
    - `scope(failure)' blocks that contain `return' statements are now
      deprecated.
    - Fix regression where wrong cast was inserted for ternary operator
      and non-int enums.
    - Fix internal error in code generation trying to reference
      _d_arraysetctor.
    - Fix memory corruption when array literal is passed to map in
      lambda, then returned from nested function.
    - Generate invariant id on the basis of location rather than a
      global counter.
    - Make `noreturn' conversions work.
    - Fix segfault when `.stringof' of template alias overloaded with
      function accessed by trait.
    - Empty array literal passed to scope param not 'falsey' anymore.

Phobos changes:

    - Avoid copying ranges in std.algorithm.comparison.equal.
