It hasn't seen active development in years, and it hasn't reached a
state where it was useful.
Remove the code until someone is interested in working on it again.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The definitions in sanitizer_common may conflict with definitions from system headers because:
The runtime includes the system headers after the project headers (as per LLVM coding guidelines).
lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT
This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

Summary:
Adds a global variable to specify the tool, to support handling early
interceptors that invoke instrumented code, thus requiring shadow memory to
be initialized prior to __esan_init() being invoked.

Summary:
Adds the base runtime library for the working set tool.
Adds slowpath code for updating the shadow memory.
To be added in the future:
+ Scan memory and report the total size.
+ Take samples for intermediate values.

Summary:
Adds processCompilationUnitInit and processCompilationUnitExit
for compilation unit init/exit.
Adds a tool-specific argument passed to esan_init.
Adds the dtor and esan_exit called from the dtor.
A test will be added separately (adding it here results in failure until
the corresponding compilation patch is in place).

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.
