Wmisleading-indentation: add reproducer for PR c/70085

PR c/70085 reported a false-positive from -Wmisleading-indentation.

The warning was fixed by the fix for PR c/68187 (r233972), but it seems
worth capturing the reproducer for PR c/70085 as an additional test case,
as it's slightly different to those seen in PR c/68187.

gcc/testsuite/ChangeLog:
	PR c/70085
	* c-c++-common/Wmisleading-indentation.c (pr70085): New test case.
