The filename part in the message header is used by Visual Studio
to fill Error List so that a user can click on an item and jump
to the mentioned location. If we use only the name of a source file
and not the full path, Visual Studio might be unable to find the right
file or, even worse, show a wrong one.

D65213 (rL367536) does not work for the case when a source file path
includes subdirectories.

1. raw_ostream supports ANSI colors so that you can write messages to
the termina with colors. Previously, in order to change and reset
color, you had to call `changeColor` and `resetColor` functions,
respectively.
So, if you print out "error: " in red, for example, you had to do
something like this:
OS.changeColor(raw_ostream::RED);
OS << "error: ";
OS.resetColor();
With this patch, you can write the same code as follows:
OS << raw_ostream::RED << "error: " << raw_ostream::RESET;
2. Add a boolean flag to raw_ostream so that you can disable colored
output. If you disable colors, changeColor, operator<<(Color),
resetColor and other color-related functions have no effect.
Most LLVM tools automatically prints out messages using colors, and
you can disable it by passing a flag such as `--disable-colors`.
This new flag makes it easy to write code that works that way.

We extract and print the source location in the message header so that
Visual Studio is able to parse it and jump there. As duplicate symbols
are defined in several locations, it is more convenient to have separate
error messages, which allows a user to easily access all the locations.

Previously, when `--vs-diagnostics` was used, the linker printed
something like
hidden(undef.s): error: undefined hidden symbol: foo
>>> referenced by undef.s:15

Summary:
This could previously happen if errors that are emitted after reaching the
error limit. In that case, the flag inside the newline() function will be
set to true which causes the next call to print a newline even though the
actual message will be discarded.

This patch does the same thing as r365595 to other subdirectories,
which completes the naming style change for the entire lld directory.
With this, the naming style conversion is complete for lld.

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.

- 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

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

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.
llvm-svn: 318060
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.
