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.

Clement Courbet eee2e06e2a [llvm-exegesis][NFC] Add a way to declare the default counter binding for unbound CPUs for a target.
Summary:
This simplifies the code and moves everything to tablegen for consistency. This
also prepares the ground for adding issue counters.

Clement Courbet 41c8af3924 [MCSched] Bind PFM Counters to the CPUs instead of the SchedModel.
Summary:
The pfm counters are now in the ExegesisTarget rather than the
MCSchedModel (PR39165).

This also compresses the pfm counter tables (PR37068).

Clement Courbet 4860b98443 [llvm-exegesis] Get the BenchmarkRunner from the ExegesisTarget.
Summary:
This allows targets to override code generation for some instructions.
As an example of override, this also moves ad-hoc instruction filtering
for X86 into the X86 ExegesisTarget.
