Patch V2: adds new patch.
Patch V3: `%{mmips16e2} \` puts the wrong palce in first patch,
V3 fix it.

The MIPS16e2 ASE is an enhancement to the MIPS16e ASE,
which includes all MIPS16e instructions, with some addition.

This series of patches adds all instructions from MIPS16E2 ASE
with corresponding tests.

Jie Mei (9):
  MIPS: Add basic support for mips16e2
  MIPS: Add MOVx instructions support for mips16e2
  MIPS: Add instruction about global pointer register for mips16e2
  MIPS: Add bitwise instructions for mips16e2
  MIPS: Add LUI instruction for mips16e2
  MIPS: Add load/store word left/right instructions for mips16e2
  MIPS: Use ISA_HAS_9BIT_DISPLACEMENT for mips16e2
  MIPS: Add CACHE instruction for mips16e2
  MIPS: Make mips16e2 generating ZEB/ZEH instead of ANDI under certain
    conditions
