- **[Inliner] Propagate more attributes to params when inlining**
Add support for propagating:
- `derefereancable`
- `derefereancable_or_null`
- `align`
- `nonnull`
- `range`
These are only propagated if the parameter to the to-be-inlined callsite
match the exact parameter used in the to-be-inlined function.
A struct that declares an inner struct, but no fields, won't have a
field count. So getting the offset of the inner struct fails. This
happens in both C and C++:
struct foo {
struct bar {
int Quantizermatrix[];
};
};
Here 'struct foo' has no fields.
