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.

Summary:
This check uses the context of a subtraction expression as well as knowledge
about the Abseil Time types, to infer the type of the second operand of some
subtraction expressions in Duration conversions. For example:
absl::ToDoubleSeconds(duration) - foo
can become
absl::ToDoubleSeconds(duration - absl::Seconds(foo))
This ensures that time calculations are done in the proper domain, and also
makes it easier to further deduce the types of the second operands to these
expressions.
