Cleanup: Platform CPU enum, MachineDescription,

Platform:
  - enum CPUFamily is part of CPUType
  - DALVIK -> ANDROID
  - ARM: ARM + ARMv[567]

MachineDescription
   - self contained
   - static size/alignment Config (enum) for unix32, unix64, win32, win64 and armeabi
   - add 'long double'
   - Removed MachineDescription32Bit, MachineDescription64Bit
   - createStatic(..) uses OS/CPU to fetch best match if not at runtime

FIXES: JavaEmitter's struct-emit: Proper 32/64 struct sizes

TODO: StructAccessor's mapping to <Type>Buffer w/ index os sizeof(<Type>)
      doesn't work, since offset may not be multiple of sizeof(<Type>)!

i.e.
typedef struct {
    int8_t bits1;  // +1       -   0
                   // +3 (p32)
    int32_t id;    // +4       -   4
    int8_t bits2;  // +1       -   8
                   // +3 (p32) -
    int64_t long0; // +8       -  12

so "longBuffer.get(<type-sized index>)" is invalid,
but "byteBuffer.getLong(<byte index>)" must be done.

The actual impl. doesn't matter, hence dropping the other nio type mappings is good.
