unit-tests: add if_test
The macro TEST only allows defining a test that consists of a single
expression. Add a new macro, if_test, which provides a way to define
unit tests that are made up of one or more statements.
if_test allows defining self-contained tests en bloc, a bit like
test_expect_success does for regular tests. It acts like a conditional;
the test body is executed if test_skip_all() had not been called before.
