b2d5fc3e66 - some of the __attribute__((regparm())) were missed in the fpu .c files 
when converting to the BX_CPP_AttrRegparm macro.

50efc3b8c7 - apply Conn Clark's patch.perf-regparm-cclark : 
- it works only on x86 with gcc2.95+
  - uses the GCC function atribute "regparm(n)" to declare that certain
    functions use the register calling convention
  - performance improvement is about 6%

b514c71079 - apply patch [ 658950 ] Bug in FPU 
Here are comments from the anonymous patch author :
  I found bug when using the FPU in 16 bit protected
  mode. When using the fsave command the 32bit
  structures were used instead of the 16bit ones.

  It now distinguishes between 16 and 32 bit protected mode
  which wasn't the case before.

  Now Ultima8 runs fine:)
