Processor-specific builds

[GoogleCodeExporter]

In the same manner as !TenFourFox, offer processor-optimized builds (likely 
6xx, G3 and G4). However, this will require some work on the .mcps to have 
processor-specific targets.

Investigate and try to implement for 9.3.1. Drop milestone if not useful.

We need a call in the library somewhere to get and cache whether AltiVec is 
enabled. It should cache it because we don't need to keep calling Gestalt() 
when we already know. The below code will do this at runtime.

00013 enum {
00014     gestaltPowerPCProcessorFeatures = 'ppcf',
00015     gestaltPowerPCHasGraphicsInstructions = 0,
00016     gestaltPowerPCHasSTFIWXInstruction = 1,
00017     gestaltPowerPCHasSquareRootInstructions = 2,
00018     gestaltPowerPCHasDCBAInstruction = 3,
00019     gestaltPowerPCHasVectorInstructions = 4,
00020     gestaltPowerPCHasDataStreams = 5
00021 };
00022 */
00023 
00024 long _jit_altivec=0;
00025 
00026 long jit_altivec_capable(void)
00027 {
00028 #if JIT_CAN_ALTIVEC
00029     long processorAttributes;
00030     Boolean result = false;
00031     OSErr err = Gestalt( 'ppcf' /* gestaltPowerPCProcessorFeatures */ , 
&processorAttributes);
00032     if( err == noErr )
00033     result = (1 << 4 /* gestaltPowerPCHasVectorInstructions */) 
&processorAttributes;
00034     return result;
00035 #else
00036     return 0;
00037 #endif //WIN_VERSION
00038 }

Logically we should put this into nsprpub/pr/src/md/mac/maccpu.c with a getter 
function to see if the result has been memoized, and if not, get and cache it. 
We will also need a maccpu.h for those files that want it in the same folder.

Dropping, we have 9.3.1 too delayed
