<pre>Compiling 32 bit Mesa with GCC 7.x and -O1 results in a number of test failures
in piglit (e.g. packUnorm2x16).
These tests do *not* fail in either of the following cases:
1) Mesa is compiled with GCC 7 and the -mfpmath=sse flag
2) Mesa is compiled with GCC 6.x
3) Mesa is compiled with -O0
Compiling Mesa with GCC 7 and negating the (exposed) options (e.g.
-fno-<option>) that are enabled by -O1 still results in a failure. These
options were collected from the output of: gcc -Q --help=optimizers -O1|grep
enabled</pre>
