tests/tcg: update licenses to GPLv2 as intended

My default header template is GPLv3 but for QEMU code we really should
stick to GPLv2-or-later (allowing others to up-license it if they
wish). While this is test code we should still be consistent on the
source distribution.

I wrote all of this code so its not a problem. However there remains
one GPLv3 file left which is the crt0-tc2x.S for TriCore.

tests/tcg: add float_convd test

This is a simple transliteration of the float_convs test but this time
working with doubles. I'm used it to test the handling of vector
registers in gdbstub but wasn't able to find a non-ugly way to
automate it.
