The following patch tries to consolidate the -O3 torture testing
options in the attempt to reduce testing time while not losing
coverage.
It drops testing of -funroll-all-loops (which nobody should use)
and retains only one non-default -O3 set of options - namely
-O3 plus those flags that would be enabled by -fprofile-use.
One should hope for ~20% less time in the C and dg tortures this way.
Didn't look into other tortures to apply the same yet (objc-torture?)
Currently testing on x86_64-unknown-linux-gnu.
For weird flag combinations we do have contributors that test
them and regularly report bugzillas.
Ok?
Comments?
Thanks,
Richard.

* lib/c-torture.exp (C_TORTURE_OPTIONS): Remove
{ -O3 -fomit-frame-pointer },
{ -O3 -fomit-frame-pointer -funroll-loops } and
{ -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions }
in favor of
{ -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer
-finline-functions }
* lib/gcc-dg.exp (DG_TORTURE_OPTIONS): Likewise.
