Instead I would do the same thing I did for tasks.
Generate captured function as is. But also create the second function with the
profile required for target codegen. This function must gather all its
parameters into a single record and then call auto generated captured function.
This captured function must be marked as AlwaysInline.
In this case you don't need to make some additional changes in Sema for
particular processing of target directives, you will just need to generate
simple function in codegen.
This may result in a little bit slower performance, but we may improve it
later, when we have time to improve codegen for outlined functions for
CapturedDecls.
I don't like the idea of reinventing of features, that are invented already,
like capturing of VLAs, exposing some private functions (like getVLASizeMap())
etc.
so the code would be like this:
```
void .omp_outlined.(%captures *ptr) always_inline {
<captured code>;
}
void .target_omp_outlined.(int* a, float* b, ...) {
%captures rec;
rec.a_ref = a;
rec.b_ref = b;
...
.omp_outlined.(&rec);
}
```

It would be good to see the tests for 32 bit target.
