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.

`FlatByteMap`, and `TwoLevelByteMap`.
Summary:
This is a follow up patch to r346956 for the `SizeClassAllocator32`
allocator.
This patch makes `AddressSpaceView` a template parameter both to the
`ByteMap` implementations (but makes `LocalAddressSpaceView` the
default), some `AP32` implementations and is used in `SizeClassAllocator32`.
The actual changes to `ByteMap` implementations and
`SizeClassAllocator32` are very simple. However the patch is large
because it requires changing all the `AP32` definitions, and users of
those definitions.
For ASan and LSan we make `AP32` and `ByteMap` templateds type that take
a single `AddressSpaceView` argument. This has been done because we will
instantiate the allocator with a type that isn't `LocalAddressSpaceView`
in the future patches. For the allocators used in the other sanitizers
(i.e. HWAsan, MSan, Scudo, and TSan) use of `LocalAddressSpaceView` is
hard coded because we do not intend to instantiate the allocators with
any other type.
In the cases where untemplated types have become templated on a single
`AddressSpaceView` parameter (e.g. `PrimaryAllocator`) their name has
been changed to have a `ASVT` suffix (Address Space View Type) to
indicate they are templated. The only exception to this are the `AP32`
types due to the desire to keep the type name as short as possible.
In order to check that template is instantiated in the correct a way a
`static_assert(...)` has been added that checks that the
`AddressSpaceView` type used by `Params::ByteMap::AddressSpaceView` matches
the `Params::AddressSpaceView`. This uses the new `sanitizer_type_traits.h`
header.

Summary:
The `TestOnlyInit` function of `{Flat,TwoLevel}ByteMap` seems to be a misnomer
since the function is used outside of tests as well, namely in
`SizeClassAllocator32::Init`. Rename it to `Init` and update the callers.
