[libFuzzer] simplify the DFT trace collection using the new faster DFSan mode that traces up to 16 labels at a time and never runs out of labels. Second attempt.

It broke the Windows build:
C:\b\s\w\ir\cache\builder\src\third_party\llvm\compiler-rt\lib\fuzzer\FuzzerDataFlowTrace.cpp(243): error C3861: 'setenv': identifier not found
This also reverts the follow-up r363327.

[libFuzzer] Fix DataFlow.cpp logic when tracing long inputs.2019-04-12T21:00:12+00:00Max Morozmmoroz@chromium.org2019-04-12T21:00:12+00:00urn:sha1:b6e6d3c740a4b94a64ad62745a18571f1a9cb3cb
Summary:
1. Do not create DFSan labels for the bytes which we do not trace. This is where we run out of labels at the first place.
2. When dumping the traces on the disk, make sure to offset the label identifiers by the number of the first byte in the trace range.
3. For the last label, make sure to write it at the last position of the trace bit string, as that label represents the input size, not any particular byte.
Also fixed the bug with division in python which I've introduced when migrated the scripts to Python3 (`//` is required for integral division).
Otherwise, the scripts are wasting too much time unsuccessfully trying to
collect and process traces from the long inputs. For more context, see

Update the file headers across all of the LLVM projects in the monorepo2019-01-19T08:50:56+00:00Chandler Carruthchandlerc@gmail.com2019-01-19T08:50:56+00:00urn:sha1:2946cd701067404b99c39fb29dc9c74bd7193eb3
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.
