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.

fc51490baf Lift VFS from clang to llvm (NFC)
This patch moves the virtual file system form clang to llvm so it can be
used by more projects.

Concretely the patch:
 - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
 - Moves the corresponding unit test from clang to llvm.
 - Moves the vfs namespace from clang::vfs to llvm::vfs.
 - Formats the lines affected by this change, mostly this is the result of
   the added llvm namespace.

c205d8cc8d [clang] Change std::sort to llvm::sort in response to r327219
r327219 added wrappers to std::sort which randomly shuffle the container before
sorting.  This will help in uncovering non-determinism caused due to undefined
sorting order of objects having the same key.

To make use of that infrastructure we need to invoke llvm::sort instead of
std::sort.

e86a5f4c65 Make llvm::Error generated from replacement interfaces more specific.
Summary:
The new error information contains the type of error (e.g. overlap or bad file path)
and the replacement(s) that is causing the error. This enables us to resolve some errors.
For example, for insertion at the same location conflict, we need to know the
existing replacement which conflicts with the new replacement in order to calculate
the new position to be insert before/after the existing replacement (for merging).

6ef82b6754 Merge conflicting replacements when they are order-independent.
Summary:
Now two replacements are considered order-independent if applying them in
either order produces the same result. These include (but not restricted
to) replacements that:
  - don't overlap (being directly adjacent is fine) and
  - are overlapping deletions.
  - are insertions at the same offset and applying them in either order
    has the same effect, i.e. X + Y = Y + X if one inserts text X and the
    other inserts text Y.

Discussion about this design can be found in D24717

e990652542 When replacements have the same offset, make replacements with smaller length order first in the set.
Summary:
No behavioral change intended. The change makes iterating the replacements set more intuitive in Replacements class implementation. Previously, insertion is ordered before an deletion/replacement with the same offset, which is counter-intuitive for implementation, especially for a followup patch to support adding insertions around replacements.

With the current ordering, we only need to make `applyAllReplacements` iterate the replacements set reversely when applying them so that deletion/replacement is still applied before insertion with the same offset.

ac73ea34a4 Supports adding insertion around non-insertion replacements.
Summary:
Extend `tooling::Replacements::add()` to support adding order-independent replacements.

Two replacements are considered order-independent if one of the following conditions is true:
  - They do not overlap. (This is already supported.)
  - One replacement is insertion, and the other is a replacement with
    length > 0, and the insertion is adjecent to but not contained in the
    other replacement. In this case, the replacement should always change
    the original code instead of the inserted text.

Summary:
- Implement clang::tooling::Replacements as a class to provide interfaces to
  control how replacements for a single file are combined and provide guarantee
  on the order of replacements being applied.
- tooling::Replacements only contains replacements for the same file now.
  Use std::map<std::string, tooling::Replacements> to represent multi-file
  replacements.
- Error handling for the interface change will be improved in followup patches.

b12e5a5ccd Add functions to apply replacements and reformat them.
This is a commonly useful feature to have, and we have implemented it
multiple times with different kinds of bugs. This implementation
centralizes the idea in a set of functions that we can then use from the various
tools.

Reverts r262234, which is a revert of r262232, and puts the functions
into FOrmat.h, as they are closely coupled to clang-format, and we
otherwise introduce a cyclic dependency between libFormat and
libTooling.

cac8fc2329 [Tooling] Remove dead code.
It took me some time to figure out why this is not working as expected:
std:error_code converts to true if there is an error. This means we never
ever took the generated absolute path, which happens to be the right thing
anyways as it properly works with virtual files. Just remove the whole
thing, relative paths are covered by existing tooling tests.
