[PATCH] D111538: [X86] Prefer VEX encoding in X86 assembler.

[Pengfei Wang via Phabricator via llvm-commits]

pengfei added a comment.

How about we add a `EncodingCost` to the base class `Instruction` and set a high cost for EVEX? Or we can reuse the `Size` in it, since all X86 instructions set it to 0. We can use it as the encoding cost.
