[Implemented] Constant '#PB_Compiler_CPUType'

[PureLust]

A constant for the CPU-Type (basically to differ Intel / PPC) whould be nice if someone uses ASM within his Code.

So far Windows & Linux = Intel and OSX & Amiga = Other (both PPC?).
But PB-OSX may run on Intel in the future as well.

[codemaniac]

Old Amigas have m68k CPUs, but the newer ones have PPC CPUs (AmigaOne)
There also was Amigas with both CPUs and a WarpUp program to make use of the PCC CPU.

Last time I checked the Amiga version of PureBasic with AmigaOS 3.9 and it worked pretty well (m68k CPU)
