GCC maintainers: The following patch adds support for some missing instances of builtins, vec_mergee, vec_mergeo, vec_float2. This patch adds the missing GCC functionality and test cases for the builtins. The patch has been run on: powerpc64le-unknown-linux-gnu (Power 8 LE) powerpc64le-unknown-linux-gnu (Power 8 BE) powerpc64le-unknown-linux-gnu (Power 9 LE) without regressions. Please let me know if the following patch is acceptable. Thanks. Carl Love
