x86_64: Hard Float ABI support in QCG
This patch shows our efforts on resolving the ART limitations:
- passing "float"/"double" arguments via FPR
- passing "long" arguments via single GPR, not pair
- passing more than 3 agruments via GPR.
Work done:
- Extended SpecialTargetRegister enum with kARG4, kARG5, fARG4..fARG7.
- Created initial LoadArgRegs/GenDalvikX/FlushIns version in X86Mir2Lir.
- Unlimited number of long/double/float arguments support
- Refactored (v2)
