[DAGCombine] Remove the getNegatibleCost to avoid the out of sync with getNegatedExpression

[asan_symbolize] Fix bug handling C++ symbols when using Atos.
Summary:
The previous code tries to strip out parentheses and anything in between
them. I'm guessing the idea here was to try to drop any listed arguments
for the function being symbolized. Unfortunately this approach is broken
in several ways.
* Templated functions may contain parentheses. The existing approach
messes up these names.
* In C++ argument types are part of a function's signature for the
purposes of overloading so removing them could be confusing.
Fix this simply by not trying to adjust the function name that comes
from `atos`.
A test case is included.
Without the change the test case produced output like:
```

[analyzer][NFC] Merge checkNewAllocator's paramaters into CXXAllocatorCall
Party based on this thread:
http://lists.llvm.org/pipermail/cfe-dev/2020-February/064754.html.
This patch merges two of CXXAllocatorCall's parameters, so that we are able to
supply a CallEvent object to check::NewAllocatorCall (see the description of
D75430 to see why this would be great).
One of the things mentioned by @NoQ was the following:
I think at this point we might actually do a good job sorting out this
check::NewAllocator issue because we have a "separate" "Environment" to hold
the other SVal, which is "objects under construction"! - so we should probably
simply teach CXXAllocatorCall to extract the value from the
objects-under-construction trait of the program state and we're good.
I had MallocChecker in my crosshair for now, so I admittedly threw together
something as a proof of concept. Now that I know that this effort is worth
pursuing though, I'll happily look for a solution better then demonstrated in
this patch.

constructor is hazardous, because the construction time is unclear and
determined by the first use. The function may be only partially
constructed, which is part of why we have many of these hacky string
attributes to track what we need for ABI lowering.
For SelectionDAG, all stack objects are created up-front before
calling convention lowering so stack objects are visible at
construction time. For GlobalISel, none of the IR function has been
visited yet and the allocas haven't been added to the MachineFrameInfo
yet. This should fix failing to set flat_scratch_init in GlobalISel

CallAndMessage also has another problem, namely that it is responsible for a lot

[mlir][StandardToSPIRV] Fix signedness issue in bitwidth emulation.
Summary:
Previously, after applying the mask, a negative number would convert to a
positive number because the sign flag was forgotten. This patch adds two more
shift operations to do the sign extension. This assumes that we're using two's
complement.
This patch applies sign extension unconditionally when loading a unspported integer width, and it relies the pattern to do the casting because the signedness semantic is carried by operator itself.

Entropic: Boosting LibFuzzer Performance
Summary:
This is collaboration between Marcel Boehme @ Monash, Australia and Valentin Manès plus Sang Kil Cha @ KAIST, South Korea.
We have made a few modifications to boost LibFuzzer performance by changing how weights are assigned to the seeds in the corpus. Essentially, seeds that reveal more "information" about globally rare features are assigned a higher weight. Our results on the Fuzzer Test Suite seem quite promising. In terms of bug finding, our Entropic patch usually finds the same errors much faster and in more runs. In terms of coverage, our version Entropic achieves the same coverage in less than half the time for the majority of subjects. For the lack of space, we shared more detailed performance results directly with @kcc. We'll publish the preprint with all the technical details as soon as it is accepted. Happy to share if you drop us an email.
There should be plenty of opportunities to optimise further. For instance, while Entropic achieves the same coverage in less than half the time, Entropic has a much lower #execs per second. We ran the perf-tool and found a few performance bottlenecks.
Thanks for open-sourcing LibFuzzer (and the entire LLVM Compiler Infrastructure)! This has been such a tremendous help to my research.

If x is +1, the result is 1.0 (even if y is a NaN).
If the absolute value of x is less than 1, and y is negative infinity, the result is positive infinity.
If the absolute value of x is greater than 1, and y is negative infinity, the result is +0.
