Reviewed by Saam Barati.
MacroAssembler::moveIntsToDouble required scratch FPRReg. But it was only required for MacroAssemblerX86, and it is already removed.
This means that we no longer need this scratch FPRReg. This change makes a lot of IC code, property access code simpler.
This patch removes that scratch FPRReg, and removed scratch FPRReg of many arithmetic ICs. This patch is important for PutByVal modern
IC since some of property access requires FPRReg because of MacroAssembler::moveIntsToDouble, and it requires adding new m_scratch2FPR
to AccessCase. But after this simplification, this is no longer necessary.
