Added implementations for ia32, arm, arm64. mips/mips64 will be committed in separate CL once the build is green again in order not to stall this CL with the supported architectures. Drive-by: Fixed issues with kScratchRegister being overwritten in case of RegExp compilation by using alternative temp register for x64. Drive-by: Added missing NoRootArrayScope to ia32, arm and arm64 RegExp macro assemblers.
