This patchs makes us run the main C vect.exp tests twice, once with the
normal optimisation options and once with -flto added. It's a simple
way of covering the LTO streaming of the new "internal" functions,
but it should be useful more generally.
The testsuite runs quickly (even cross), so an extra pass through
doesn't have much overhead.
Tested on x86_64-linux-gnu and arm-linux-gnueabi. OK to install?
