GCC Maintainers:

The following patch adds missing test cases for
vec_extract_fp32_from_shortl(), vec_extract_fp32_from_shorth(), and
vec_extract().  

The patch has been run on:

  powerpc64le-unknown-linux-gnu (Power 8 LE)
  powerpc64le-unknown-linux-gnu (Power 9 LE)

without regressions.  

Please let me know if the following patch is acceptable.  Thanks.
