Gilles Peskine fe11b72b93 Use TEST_EQUAL(a,b) in preference to TEST_ASSERT(a==b)
This commit is the result of the following command, followed by
reindenting (but not wrapping lines):

perl -00 -i -pe 's/^( *)TEST_ASSERT\(([^;=]*)(?: |\n *)==([^;=]*)\);$/${1}TEST_EQUAL($2,$3);/gm' tests/suites/test_suite_psa_*.function
