Subject: [PATCH 1/2] gallivm: add new wrapper around
Module::setOverrideStackAlignment()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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
<https://github.com/llvm/llvm-project/commit/3787ee457173c3612aac4c9b1a2b6d6ab0202616>.
Unfortunately Module::setOverrideStackAlignment() is not available
through the C API and we need to wrap it ourselves.

Subject: [PATCH 2/2] gallivm: fix FTBFS on i386 with LLVM >= 13,
StackAlignmentOverride is gone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Use the newly added wrapper lp_set_module_stack_alignment_override() to
achieve the same end result.
