[PULL 1/4] tcg/aarch64/tcg-target.opc.h: Add copyright/license

[Richard Henderson]

From: Peter Maydell <peter.maydell@linaro.org>

Add the copyright/license boilerplate for target/aarch64/tcg-target.opc.h.
This file has only had two commits: 14e4c1e2355473ccb29
and 79525dfd08262d8, both by the same Linaro engineer.
The license is GPL-2-or-later, since that's what the
rest of tcg/aarch64 uses.

[PULL 4/4] tcg/LICENSE: Remove out of date claim about TCG subdirectory licensing

[Richard Henderson]

From: Peter Maydell <peter.maydell@linaro.org>

Since 2008 the tcg/LICENSE file has not changed: it claims that
everything under tcg/ is BSD-licensed.

This is not true and hasn't been true for years: in 2013 we
accepted the tcg/aarch64 target code under a GPLv2-or-later
license statement. We also have generic vector optimisation
code under the LGPL2.1-or-later, and the TCI backend is
GPLv2-or-later. Further, many of the files are not BSD
licensed but MIT licensed.

We don't really consider the tcg subdirectory to be a distinct part
of QEMU anyway.

Remove the LICENSE file, since claiming false information
about the license of the code is confusing.

Update the main project LICENSE file also to be clearer about
the licenses used by TCG.
