Forbidding use of rbp for register allocation on x86-64 platform.

It is necessary because of bug in gcc / g++: Pointers allocated on rbp can be (are?) supposed to be aligned indepedently of what they actually contain. Turning off allocation on rbp is not critical for now, because, currently, x86-64 is just development platform.
