gallivm: add new wrapper around Module::setOverrideStackAlignment() 

We need it in the next commit to replace setting the stack alignment on
i386 with LLVM >= 13 through the TargetOption::StackAlignmentOverride,
which was removed in the upstream commit
<3787ee4571>.

Unfortunately Module::setOverrideStackAlignment() is not available
through the C API and we need to wrap it ourselves.
