GCC Maintainers:
The following patch adds tests for the vec_max builtin.
The patch for the test case was tested on
powerpc64le-unknown-linux-gnu (Power 8 LE)
powerpc64-unknown-linux-gnu (Power 8 BE)
powerpc64le-unknown-linux-gnu (Power 9 LE).
Please let me know if the patch looks OK for GCC mainline.
Carl Love
