GCC maintainers:

The patch adds documentation and test cases for the __builtin_vsx_xvnegsp, __builtin_vsx_xvnegdp built-ins.

The patch has been tested on Power 10 with no regressions.

Please let me know if this patch is acceptable for mainline.  Thanks.

                      Carl 
------------------------------------------------------------
rs6000, __builtin_vsx_xvneg[sp,dp] add documentation and test cases

Add documentation to the extend.texi file for the two built-ins
__builtin_vsx_xvnegsp, __builtin_vsx_xvnegdp.

Add test cases for the two built-ins.

gcc/ChangeLog:
	* doc/extend.texi (__builtin_vsx_xvnegsp, __builtin_vsx_xvnegdp):
	Add documentation.

gcc/testsuite/ChangeLog:
	* gcc.target/powerpc/vsx-builtin-runnable-2.c: New test case.

I think these two are useless, the functionality has been covered by vec_neg
in PVIPR, so instead we should get rid of these definitions (bif def table,
test cases if there are some).
