Update to v087r27 release.

byuu says:

Changelog:
- serialize processor.pc.data, not processor.pc
- call CPU processor.setMode() in ARM serialize
- serialize BIOS.mdr
- support SRAM > 32KB
- EEPROM, FlashROM serialize
- EEPROM lose nall/bitarray.hpp
- noise line feed after envelope
- space out PSR read
- ST018 needs byte reads fixed (don't align) [fixes HNMS2]
- flush sram/eeprom/flashrom to 0 on cartridge load
- APU/PPU dont sync back to CPU if syncing for state
- fixed APU sync problems in GB/GBC core that could possibly wreck save
  states as well

Quite a lot of little problems there. I believe GBA save states are
fixed now.
