Craig Topper c2247a32db [X86] Clzero intrinsic and its addition under znver1 ... This patch does the following. 1. Adds an Intrinsic int_x86_clzero which works with __builtin_ia32_clzero 2. Identifies clzero feature using cpuid info. (Function:8000_0008, Checks if EBX[0]=1) 3. Adds the clzero feature under znver1 architecture. 4. The custom inserter is added in Lowering. 5. A testcase is added to check the intrinsic. 6. The clzero instruction is added to assembler test. Patch by Ganesh Gopalasubramanian with a couple formatting tweaks, a disassembler test, and using update_llc_test.py from me.
