clang does not support the %v to select the AVX encoding, nor the '%d' asm contrain, and for AVX build it requires all 3 arguments. This patch add a new internal header, math-inline-asm.h, that adds functions to abstract the inline asm required differences between gcc and clang. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
