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.

Sam Clegg 3ad27e92bc Code cleanup in preparation for adding LTO for wasm. NFC.
- Move some common code into Common/rrorHandler.cpp and
  Common/Strings.h.
- Don't use `fatal` when incompatible bitcode files are
  encountered.
- Rename NameRef variable to just Name

Sam Clegg 77c1def71a Use ErrorOS for log messages as well as error
log are also diagnostics so it seems like they should to
the same place as errors and debug messages.

Without this change when I enable --verbose those messages
go to stdout, but when I enable "-mllvm -debug" those messages
go to stderr (because dbgs() goes to stderr by default).

So I end up having to do this a lot:
 lld <args> > output_message 2>&1

Rafael Espindola a4884cc38f Try harder to delete the temporary file.
It is really hard to cover restarts in a debugger, SIGKILL or power
failures. I will try to handle them in a followup patch, but it will
not support all the systems lld has to run on.

RemoveFileOnSignal takes care of crashes.

So what is left is making sure all regular exits delete the file. This
patch does that by moving the buffer to error handling. That is a bit
of a hack, but seemed better than to generalize it to take a callback on
construction.

I will implement this on COFF on the next patch.

Bob Haarman b8a59c8aa5 [lld] unified COFF and ELF error handling on new Common/ErrorHandler
Summary:
The COFF linker and the ELF linker have long had similar but separate
Error.h and Error.cpp files to implement error handling. This change
introduces new error handling code in Common/ErrorHandler.h, changes the
COFF and ELF linkers to use it, and removes the old, separate
implementations.
