Eli Friedman e24e95fe90 Remove CompositeType class.
The existence of the class is more confusing than helpful, I think; the
commonality is mostly just "GEP is legal", which can be queried using
APIs on GetElementPtrInst.

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.

Justin Bogner 7d449d31a4 Re-apply "Introduce FuzzMutate library"
Same as r311392 with some fixes for library dependencies. Thanks to
Chapuni for helping work those out!

Original commit message:

This introduces the FuzzMutate library, which provides structured
fuzzing for LLVM IR, as described in my EuroLLVM 2017 talk. Most of
the basic mutators to inject and delete IR are provided, with support
for most basic operations.

Justin Bogner 6e39755d84 Revert "Re-apply "Introduce FuzzMutate library""
The dependencies for the new library seem to be misconfigured on some
linux configs:

This reverts r311392.

Justin Bogner f5c8736482 Re-apply "Introduce FuzzMutate library"
Redo r311356 with a fix to avoid std::uniform_int_distribution<bool>.
The bool specialization is undefined according to the standard, even
though libc++ seems to have it.

Looks like this fails to build with libstdc++.

This reverts r311356

I will follow up with the instruction selection fuzzer, which is
implemented in terms of this library.
