FFI loads and stores via structs can have a TypedData as receiver,
so this CL updates those loads to `kMayBeInnerPointer`.
This CL adds an IL test to verify that for `Pointer` loads the untagged
value is treated correctly as `kCannotBeInnerPointer`.
(And adds some prefer-inline pragmas to make some common operations
be inlined to avoid allocating `Pointer` objects.)
This CL updates the load in the FFI closures to use a load-field.
This can also potentially enable not allocating a pointer object when
this closure is inlined.

CoreLibraryReviewExempt: Only adding some pragmas.
