e14d8e6611 * don't replace cmplwi's with flag-setting variants of integer operations, 
as the latter perform a signed comparison with 0

cd3f064a33 + enabled postpeepholeopts phase 
+ optimize "integer op" followed by comparison of target register with zero
    to a variant of that integer op which sets the flags (ppc)
  + change rlwinm. instructions which do nothing but an "and" operation into
    andi./andis., since the rlwinm. is cracked on the G5 while andi./andis.
    isn't

bfa2301575 * const record parameters > 8 bytes are now passed by reference for non 
cdecl/cppdecl procedures on Mac OS/Mac OS X to fix compatibility with
    GPC (slightly more efficient than Metrowerks behaviour below, but
    less efficient in most cases than our previous scheme)
  + "mwpascal" procedure directive to support the const record parameter
    behaviour of Metrowerks Pascal, which passes all const records by
    reference
