Louis Dionne ca495e36c1 [clang] Add a new flag -fexperimental-library to enable experimental library features
Based on the discussion at [1], this patch adds a Clang flag called
-fexperimental-library that controls whether experimental library
features are provided in libc++. In essence, it links against the
experimental static archive provided by libc++ and defines a feature
that can be picked up by libc++ to enable experimental features.

This ensures that users don't start depending on experimental
(and hence unstable) features unknowingly.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Petr Hosek 930d46a2ef [Driver] Support object files in addition to static and shared libraries in compiler-rt
This change introduces support for object files in addition to static
and shared libraries which were already supported which requires
changing the type of the argument from boolean to an enum.

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.

Nico Weber 0c3984ef31 Remove unused includes of clang/Config/config.h
Found by opening config.h.cmake in vim, finding all defined macros with

  /define\(01\)\? \zs[A-Za-z0-9_]*<cr>
  :%s//\=setreg('A', submatch(0), 'V')/gn<cr>
  :put A<cr>

and then joining them all with |, and passing that to

  git grep -E that_pattern 'clang/*.h' 'clang/*.cpp' 'clang/*.c'

and diffing that output with the result of

  git grep Config/config.h 'clang/*.h' 'clang/*.cpp' 'clang/*.c'

No intended behavior change.

Petr Hosek 8d612149db [Driver] Allow drivers to add multiple libc++ include paths
This allows toolchain drivers to add multiple libc++ include paths akin
to libstdc++. This is useful in multiarch setup when some headers might
be in target specific include directory. There should be no functional
change.

Konstantin Zhuravlyov e37b32c433 Driver/ToolChains: Mips -> MipsLinux
- Mips is architecture, not a toolchain
  - Might help eliminate the confusion in the future by not having header files with the same name
