    libgomp: Fix default value of GOMP_SPINCOUNT [PR 109062]

    When OMP_WAIT_POLICY is not specified, current implementation will cause
    icv flag GOMP_ICV_WAIT_POLICY unset, so global variable wait_policy
    will remain its uninitialized value. Initialize it to -1 to make
    GOMP_SPINCOUNT behavior consistent with its description.

    libgomp/ChangeLog:

            PR libgomp/109062
            * env.c (wait_policy): Initialize to -1.
            (initialize_icvs): Initialize icvs->wait_policy to -1.
            * testsuite/libgomp.c-c++-common/pr109062.c: New test.=
