Summary:
Adds support for app libraries starting slightly below 0x7f00'00000000 (the
mmap ASLR range extends down to 0x7efb'f8000000 for reasonable stack
limits) by switching to a shadow mapping offset of 0x1300'00000000.

Fixes a bug in checking the endpoint of a shadow region and removes an
invalid check (both introduced in http://reviews.llvm.org/rL269198).

Adds *stat to the common interceptors.
Removes the now-duplicate *stat interceptor from msan/tsan/esan.
This adds *stat to asan, which previously did not intercept it.

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.

This reverts commit 268440 because it breaks the windows bot.

Summary:
Replaces {} with a do..while sequence in esan's empty interceptors to allow
natural use with a trailing semicolon. The sequence uses each argument to
avoid warnings.

involved.
On linux, some architectures had an ABI transition from 64-bit long double
(ie. same as double) to 128-bit long double. On those, glibc symbols
involving long doubles come in two versions, and we need to pass the
correct one to dlvsym when intercepting them.
A few more functions we intercept are also versioned (all printf, scanf,
strtold variants), but there's no need to fix these, as the REAL() versions
are never called.

The interception context is not used by esan, but the compiler complains
about it being uninitialized all the same. We set it to null to avoid the
warning.

Summary:
Adds libc interceptors to the runtime library for the new
EfficiencySanitizer ("esan") family of tools. The interceptors cover
the memory operations in most common library calls and will be shared
among all esan tools.

Summary:
Adds the initial version of a runtime library for the new
EfficiencySanitizer ("esan") family of tools. The library includes:
+ Slowpath code via callouts from the compiler instrumentation for
each memory access.
+ Registration of atexit() to call finalization code.
+ Runtime option flags controlled by the environment variable
ESAN_OPTIONS. The common sanitizer flags are supported such as
verbosity and log_path.
+ An initial simple test.
Still TODO: common code for libc interceptors and shadow memory mapping,
and tool-specific code for shadow state updating.
