riscv64: Create InstructionSimplifierRiscv64, ShiftAdd
Create InstructionSimplifierRiscv64 optimization.
Replace Shl (1|2|3) and Add with Riscv64ShiftAdd IR instruction.
By compiling with dex2oat all the methods of applications below I got:
Facebook: 45 cases
TikTok: 26 cases
YouTube: 19 cases of the pattern.
Test: art/test/testrunner/testrunner.py --target --64 --ndebug --optimizing
