d: Merge upstream dmd 52844d4b1, druntime dbd0c874, phobos 896b1d0e1.

D front-end changes:

    - Parsing and compiling C code is now possible using `import'.
    - `throw' statements can now be used as an expression.
    - Improvements to the D template emission strategy when compiling
      with `-funittest'.

D Runtime changes:

    - New core.int128 module for implementing intrinsics to support
      128-bit integer types.
    - C bindings for the kernel and C runtime have been better separated
      to allow compiling for hybrid targets, such as kFreeBSD.

Phobos changes:

    - The std.experimental.checkedint module has been renamed to
      std.checkedint.

gcc/d/ChangeLog:

	* d-builtins.cc (d_build_builtins_module): Set purity of DECL_PURE_P
	functions to PURE::const_.

	* dmd/MERGE: Merge upstream dmd 52844d4b1.
	* expr.cc (ExprVisitor::visit (ThrowExp *)): New function.
	* types.cc (d_build_bitfield_integer_type): New function.
	(insert_aggregate_bitfield): New function.
	(layout_aggregate_members): Handle inserting bit-fields into an
	aggregate type.
