[PATCH 2/3] PR jit/64810: support DImode on arm

[David Malcolm <dmalcolm@redhat.com>]

jit_langhook_type_for_mode was failing for DImode on arm
(see via a segfault in test-expressions.c.exe in the jit testsuite).

A fix is to add handling for:
  mode == TYPE_MODE (long_long_integer_type_node)
to the existing checks.

gcc/jit/ChangeLog:
	PR jit/64810
	* dummy-frontend.c (jit_langhook_type_for_mode): Support
	TYPE_MODE (long_long_integer_type_node).
