Somehow when I print it in the runtime it shows up as garbage, but the actual
region seems to get correct values. There shouldn't be anything in-between the
arguments I'm printing and the kernel launch however so I'm stumped.

This might be some issue with the host codegen actually.

It does not look like the issue of the target code, I don't see any wrong
access for __context. Мост probably something wrong with the host

Why do you think it reads beyond __context? %2 = getelementptr inbounds
%struct.anon, ptr %1, i32 0, i32 0 points to the first element in the
__context, if I'm not missing something. If it has the wrong value,

I'm unsure how to resolve the issue of `CGF.EmitScalarExpr(NumTeams)` not

#pragma omp target teams distribute parallel for num_teams(Teams)

This patch attempts to remove the dependency on `libffi` by instead
emitting the host / CPU kernels using an aggregate struct made from the
captured context. This callows us to have a fixed
