[PATCH 0/3] x86: Optimize the encoder of the vvvv register

["Cui, Lili" <lili.cui@intel.com>]

These patches want to optimize the encoder of the vvvv register.
Previously we used Vexvvvv, SWAP_SOURCES and extension_opcode
to help encode the vvvv register, these patches simplified the
logic to only use vexvvvv and added appropriate Vexvvvv values
for the related instructions.

Cui, Lili (3):
  x86: Use vexvvvv to encode the vvvv register
  x86: Drop SwapSources
  x86: Drop using extension_opcode to encode vvvv register
