Are the ymm and xmm registers present as subregisters in the MIC architecture, and are the SSE and AVX instructions still there?

I am developing a code generator for the chip and want to know how much I can do by just changing the AVX code generator.

It would also be useful if there was a spec of the syntax used by the gnu assembler for the MIC
