Move .oat files to ELF format
Generates .oat in ELF file format using MCLinker
- Uses MCLinker IRBuilder to create a synthetic .o from OatWriter output.
- Uses new ElfFile for prelinking to support art image optimizations.
Adapted OatFile to load using dlopen, ElfFile, or memory, removing raw MemMap mechanism.
Changed image code to not assume oat data will be immediately after
image to allow space for ELF headers.
Passes test-art and works with installd.
