723f396a20 Tag %1 and %2 as both input and output 
The inline assembly modifies its input operands, so mark them as output to avoid surprises with optimization. Fixes #1292

0623636c98 Use Sandybridge daxpy kernel on Haswell and Zen for now 
The testcase from #1332 exposes a problem in daxpy_microk_haswell-2.c that is not seen with
any of the other Intel x86_64 microkernels.

6e7be06e07 Refs JuliaLang/julia#5728. Fix gemv performance bug on Haswell Mac OSX. 
On Mac OS X, it should use .align 4 (equal to .align 16 on Linux).
I didn't get the performance benefit from .align. Thus, I deleted it.
