selftests/bpf: adjust global_func15 test to validate prog exit precision Add one more subtest to global_func15 selftest to validate that verifier properly marks r0 as precise and avoids erroneous state pruning of the branch that has return value outside of expected [0, 1] value.

bpf: enforce precise retval range on program exit Similarly to subprog/callback logic, enforce return value of BPF program using more precise smin/smax range. We need to adjust a bunch of tests due to a changed format of an error message.

selftests/bpf: Convert test_global_funcs test to test_loader framework Convert 17 test_global_funcs subtests into test_loader framework for easier maintenance and more declarative way to define expected failures/successes.
