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.

Dean Michael Berris 29e16deb17 [XRay][compiler-rt] Runtime changes to support custom event logging
Summary:
This change implements support for the custom event logging sleds and
intrinsics at runtime. For now it only supports handling the sleds in
x86_64, with the implementations for other architectures stubbed out to
do nothing.

NOTE: Work in progress, uploaded for exposition/exploration purposes.

Depends on D27503, D30018, and D33032.

Tim Shen 0243eac2d8 [XRay] [compiler-rt] Stub out architectures we don't do arg1 logging on.
rL297000 forgot to include code for three architectures that appeared
since I wrote the first version. This gives them the same treatment as ARMs
have for now - write stubs and wait for someone to actually implement it.

Patched by pelikan (Martin Pelikán)!
