History
Bill Schmidt 202b6045bf [PowerPC] Implement the vclz instructions for PWR8 
Patch by Kit Barton.

Add the vector count leading zeros instruction for byte, halfword,
word, and doubleword sizes.  This is a fairly straightforward addition
after the changes made for vpopcnt:

 1. Add the correct definitions for the various instructions in
    PPCInstrAltivec.td
 2. Make the CTLZ operation legal on vector types when using P8Altivec
    in PPCISelLowering.cpp 

Test Plan

Created new test case in test/CodeGen/PowerPC/vec_clz.ll to check the
instructions are being generated when the CTLZ operation is used in
LLVM.

Check the encoding and decoding in test/MC/PowerPC/ppc_encoding_vmx.s
and test/Disassembler/PowerPC/ppc_encoding_vmx.txt respectively.
