    The method Type_conversion_expression::do_get_backend was (in some
    circumstances) creating a Bexpression for the source expression of the
    conversion and then throwing it away before using it. Fix up this
    method to insure that the call to get_backend() on the source
    expression is only made when the result will be used.

The make_field_assignment code:

      src = force_to_mode (src, mode,
		       GET_MODE_PRECISION (mode) >= HOST_BITS_PER_WIDE_INT
		       ? HOST_WIDE_INT_M1U
		       : (HOST_WIDE_INT_1U << len) - 1,
		       0);

would ignore the field length len for DImode, even though DImode can be
handled using HWIs.  I think the code should be testing len instead.

This patch adds a method:
  rich_location::fixits_cannot_be_auto_applied
for ensuring that mutually-incompatible fix-its hints don't
lead to insane output from -fdiagnostics-generate-patch.

Fix-it hints within such rich_location instances are printed
as normal by diagnostic_show_locus, but don't affect the output
of -fdiagnostics-generate-patch.
