Attached patch adds the following.
	* New AMD znver1 processor. The architecture has the below features
		* TBM, FMA4, XOP, LWP: ISAs are not supported.
		* SMAP, RDSEED, SHA, XSAVEC, XSAVES, CLFLUSHOPT, ADCX: ISAs are supported.
	* New CLZERO instruction support. 
		* clzero has opcode "0F 01 FC".
		* clzero gets enabled with CPUID, 8000_0008, EBX[0] =1.
		* clzero instruction zero's out the 64 byte cache line specified in rax. Bits 5:0 of rAX are ignored

I have added two new arch test files.
	1. arch-13.s: Lists out the new ISAs that are supported and checks it against the march option.
	2. x86-64-arch-3.s: The 64-bit version of the test.

It passes make check on x86-64. Okay to commit?
