Update the file headers across all of the LLVM projects in the monorepo
...
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.

[asan] Fix shifting compiler warnings when compiler in 64-bits
...
Summary:
The MSVC compiler complains about implicit conversion of 32-bits constant to
64-bit when using this shiting pattern 1 << (<64-bit expr>).

Revert "Apply modernize-use-default to compiler-rt."
...
This reverts commit r250823.
Replacing at least some of empty
constructors with "= default" variants is a semantical change which we
don't want. E.g. __tsan::ClockBlock contains a union of large arrays,
and it's critical for correctness and performance that we don't memset()
these arrays in the constructor.
