Reid Kleckner f52e2f3ef5 [Allocator] Remove memory poisoning before deallocation 
I added the poisoning back in r76891 (2009) because of some bugs in
Unladen Swallow, and then Evan Cheng added the setRangeWritable() call
in r81308. Profiling a Release+Asserts build on Windows shows that this
memory protection call is actually very expensive. 4 seconds of a 70
second Clang compilation are spent in VirtualQuery. These days we have
more reliable tools like ASan to find these kinds of bugs, so we can go
ahead and retire these checks.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
