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.

Fangrui Song 32401afd8c [llvm-exegesis] Move namespace exegesis inside llvm::
Summary:
This allows simplifying references of llvm::foo with foo when the needs
come in the future.

Clement Courbet 4273e1e828 [llvm-exegesis] Print the whole snippet in analysis.
Summary:
On hover, the whole asm snippet is displayed, including operands.

This requires the actual assembly output instead of just the MCInsts:
This is because some pseudo-instructions get lowered to actual target
instructions during codegen (e.g. ABS_Fp32 -> SSE or X87).

Clement Courbet 7228721b30 [llvm-exegesis] Analysis: Show inconsistencies between checked-in and measured data.
Summary:
We now highlight any sched classes whose measurements do not match the
LLVM SchedModel. "bad" clusters are marked in red.

Clement Courbet 448550d947 [llvm-exegesis] Analysis: detect clustering inconsistencies.
Summary:
Warn on instructions that should have the same performance
characteristics according to the sched model but actually
differ in their benchmarks.

Next step: Make the display nicer to browse, I was thinking maybe html.

Clement Courbet 37f0ca0328 [llvm-exegesis] Add an analysis mode.
Summary:
The analysis mode gives the user a clustered view of the measurement results.
Next steps are (requires the split ok AsmTemplate.Name into {mnemonic, mode}):
 - Show the sched class.
 - Highlight any inconsistencies with the checked-in data.
