rs6000: Make some BIFs vectorized on P10

This patch is to add the support to make vectorizer able to
vectorize some built-in function scalar versions on Power10.

gcc/ChangeLog:

	* config/rs6000/rs6000.c (rs6000_builtin_md_vectorized_function): Add
	support for built-in functions MISC_BUILTIN_DIVWE, MISC_BUILTIN_DIVWEU,
	MISC_BUILTIN_DIVDE, MISC_BUILTIN_DIVDEU, P10_BUILTIN_CFUGED,
	P10_BUILTIN_CNTLZDM, P10_BUILTIN_CNTTZDM, P10_BUILTIN_PDEPD and
	P10_BUILTIN_PEXTD on Power10.

gcc/testsuite/ChangeLog:

	* gcc.target/powerpc/dive-vectorize-1.c: New test.
	* gcc.target/powerpc/dive-vectorize-1.h: New test.
	* gcc.target/powerpc/dive-vectorize-2.c: New test.
	* gcc.target/powerpc/dive-vectorize-2.h: New test.
	* gcc.target/powerpc/dive-vectorize-run-1.c: New test.
	* gcc.target/powerpc/dive-vectorize-run-2.c: New test.
	* gcc.target/powerpc/p10-bifs-vectorize-1.c: New test.
	* gcc.target/powerpc/p10-bifs-vectorize-1.h: New test.
	* gcc.target/powerpc/p10-bifs-vectorize-run-1.c: New test.
