* i386: Somewhat optimized fpc_mul_qword routine, got rid from variable 'r', registers esi and edi. Also ignore overflow checking when both operands have their high dwords equal to zero, because in such case multiplication cannot overflow.

* Fixed spilling of 3-operand IMUL instruction (went unnoticed this far because such instructions were not emitted by compiler).

+ i386: inline 64-bit multiplications if overflow checking is disabled and not optimizing for size. Rough testing on Core 2 Duo shows speed improvement by factor of 5, even despite inlined code does not check for zero upper dwords.

+ Added method taddnode.use_generic_mul64bit, allowing it to inline full 64-bit multiplications, and fixed ARM to comply (it was not checking for possible 32x32 to 64 optimization after detecting a 64-bit operand, so recently added code for 32x32 to 64 bit optimization was inactive).
