Chandler Carruth 2946cd7010 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.

Sagar Thakur 2ce2ab3a4d [ESan][MIPS] Fix tests struct-simple.cpp on MIPS
For mips assember '#' is the start of comment. We get assembler error messages if # is used in the struct names. Therefore using '$' which works for all architectures.

Derek Bruening dec4bd0838 [esan] Add __esan_report for mid-run data
Summary:
Adds a new public interface routine __esan_report() which can be used to
request profiling results prior to abnormal termination (e.g., for a server
process killed by its parent where the normal exit does not allow for
normal result reporting).

Implements this for the working-set tool.  The cache frag tool is left
unimplemented as it requires missing iteration capabilities.

Adds a new test.
