[esan] EfficiencySanitizer shadow memory
Summary:
Adds shadow memory mapping support common to all tools to the new
Efficiencysanitizer ("esan") family of tools. This includes:
+ Shadow memory layout and mapping support for 64-bit Linux for any
power-of-2 scale-down (1x, 2x, 4x, 8x, 16x, etc.) that ensures that
shadow(shadow(address)) does not overlap shadow or application
memory.
+ Mmap interception to ensure the application does not map on top of
our shadow memory.
+ Init-time sanity checks for shadow regions.
+ A test of the mmap conflict mechanism.
