FP exceptions, -DNOREG for -O0 and -DBG compiles, perf tweaks, gcov

Browse Source 
reworked ring/register fix so that Primos nevers sees RP faulted
  but we don't have to do extra tests in the fetch loop
changed EAxxx routines to use RP segno when EA = register
added FP exception fault to ieeepr8 and all FP routines
added round flag to ieeepr8 (though not sure it's rounding correctly)
used gcov info to reorder some stuff in ea16s, ea32s, ea32r64r
changed warn() and fatal() to use get16t; prevpc might be a register
IMPORTANT NOTE: to compile with -O0, also use -DNOREG (gcc bug)
