updated patch
lto1 also does not get -fopenmp[-simd] passed, not sure if that is needed
though.
The simple testcase from comment #2 already fails with
> ./xgcc -B. -B ../x86_64-unknown-linux-gnu/libgomp/ -B
> ../x86_64-unknown-linux-gnu/libgomp/.libs -O -flto -fopenmp t.i -r -nostdlib
t.i: In function 'foo':
t.i:1:6: internal compiler error: in expand_GOMP_SIMD_VF, at internal-fn.c:137
void foo(int n)
^
0x8c4d19 expand_GOMP_SIMD_VF
updated patch attached that fixes the streaming and thus runs the vectorizer
at -O1 during LTRANs (but it does nothing).
