tests/tcg/i386: add runner for test-i386-fprem
The runner needs to compare against a reference run. We also only run this test when SPEED=slow as it takes a while. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
