jit: fix startup on aarch64
libgccjit fails on startup on aarch64 (and probably other archs).
The issues are that
(a) within jit_langhook_init the call to
targetm.init_builtins can use types that aren't representable
via jit::recording::type, and
(b) targetm.init_builtins can call lang_hooks.decls.pushdecl, which
although a no-op for libgccjit has a gcc_unreachable.
Fixed thusly.
gcc/jit/ChangeLog:
* dummy-frontend.cc (tree_type_to_jit_type): For POINTER_TYPE,
bail out if the inner call to tree_type_to_jit_type fails.
Don't abort on unknown types.
(jit_langhook_pushdecl): Replace gcc_unreachable with return of
NULL_TREE.
