changed: 64bit asm code didn't want to compile

Browse Source 
there were used 'lahf' and 'sahf' instructions
         probably they are supported in a new version of GCC
         with '-msahf' option but GCC 4.2.1 has no such option
         at the moment I'm using opcodes:
            lahf -> 9f
            sahf -> 9e
         Warning! these instructions are not on all 64bit processors
         from: http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html
         "Early Intel CPUs with Intel 64 lacked LAHF and SAHF instructions supported
          by AMD64 until introduction of Pentium 4 G1 step in December 2005."
changed: UInt::Add on 64bit platform
changed: UInt::Add on 32bit platform (a little)
