Ouch, I'll actually need to insert new parameters in the middle, because say
for SSE2
#pragma omp declare simd simdlen (4) inbranch
int foo (int x, long long y, int z);
is passed as
vector(4) int foo (vector(4) int x, vector(2) long long y,
vector(2) long long y2nd, vector(4) int z,
vector(4) int mask);
and thus I need to modify the first and second argument, then
insert a new argument after second, then modify third argument and add
another argument at the end.
