[PATCH, rs6000] testcase coverage for vec_cntlz

[Will Schmidt <will_schmidt at vnet dot ibm dot com>]

Hi, 

[PATCH, rs6000] testcase coverage for vec_cntlz

Add testcase coverage for vec_cntlz built-in functions.

Tested across power platforms (p6 and newer).  
OK for trunk?

Thanks,
-Will

	* fold-vec-cntlz-char.c: New.
	* fold-vec-cntlz-short.c: New.
