changed get/put(16,32)r to check for ring change and use regular
get/put call if possible, so brp supercache can be used
FUTURE: could add separate brp cache entry for R0 accesses
changed ea32r64r live register test so normal path is first
changed ea64v live register test so normal path is first
change ea32i to use INCRP macro instead of RPL++
added INCRP macro - now does 32-bit increments of RP for speed
added ADDRP macro to return RP incremented by n (CGT)
changed globals to static (didn't help speed much - thought it might)
moved around some functions
changed shift instructions to create bitmask at runtime (faster)
manually inlined mathexception (but used inline keyword in later revs)
huge hunk of 32I instructions
generalized SETCC and LCXX macros so I-mode can use them
fixed bug in LDC where A-reg was getting trashed at end of string
made macros for many instructions so I-mode can use them
forgot to close the boot file
