[PATCH] D22993: [MSAN][MIPS] Changed memory mapping to support pie executable.

[Evgeniy Stepanov via llvm-commits]

How about this:
MEM_TO_SHADOW = x ^ 0x800...
SHADOW_TO_ORIGIN = x + 0x200...
and
0x0000000000-0x0200000000: Program own segments
0xa200000000-0xc000000000: PIE program segments
0xe200000000-0xffffffffff: libraries segments.

That's about 2x more address space, and I don't see any overlaps.
