I'm unsure how to resolve the issue of `CGF.EmitScalarExpr(NumTeams)` not
returning the correct value now. For the following code
```c
#include <stdio.h>
#include <stdlib.h>
int main() {
int Teams = 10;
#pragma omp target teams distribute parallel for num_teams(Teams)
for (int i = 0; i < 1; ++i)
;
return 0;
}
```
I get this LLVM-IR, which suggests that it's reading beyond the expected
`__context` struct.
```llvm
; Function Attrs: convergent noinline norecurse nounwind optnone uwtable
define weak_odr protected void @__omp_offloading_10302_af886a3_main_l9(ptr
noalias noundef %dyn_ptr, ptr noalias noundef %__context) #0 {
entry:
%dyn_ptr.addr = alloca ptr, align 8
%__context.addr = alloca ptr, align 8
%.capture_expr. = alloca i32, align 4
%0 = call i32 @__kmpc_global_thread_num(ptr @3)
store ptr %dyn_ptr, ptr %dyn_ptr.addr, align 8
store ptr %__context, ptr %__context.addr, align 8
%1 = load ptr, ptr %__context.addr, align 8
%2 = getelementptr inbounds %struct.anon, ptr %1, i32 0, i32 0
%3 = load i32, ptr %2, align 4
store i32 %3, ptr %.capture_expr., align 4
%4 = load i32, ptr %.capture_expr., align 4
call void @__kmpc_push_num_teams(ptr @3, i32 %0, i32 %4, i32 0)
call void (ptr, i32, ptr, ...) @__kmpc_fork_teams(ptr @3, i32 0, ptr
@__omp_offloading_10302_af886a3_main_l9.omp_outlined)
ret void
}
```
Any idea how to resolve this? I'm assuming the way we do this now is no longer
valid somehow because of the struct indirection.
