Added VMSPLIT_2G support.

Change-Id: Ic774271f21d2c45d04f239a3665308dd4db59fee
enable support for large files (> 2G)

bionic has an i386 ifdef guard for the O_LARGEFILE flag. The reason for this
is not traceable in the git history, but it's most likely due to some old
toolchain or emulator problem.
