[vm/ffi] Add class to vm:ffi:struct-fields pragma
Browse files Browse the repository at this point in the history 
This CL changes `@pragma('vm:ffi:struct-fields', [...])` to
`@pragma('vm:ffi:struct-fields', _FfiStructLayout([...]))` which makes
it easier to add more data in subsequent CLs.

Extends `FindPragma` to allow returning multiple matched pragma's, so
that we can filter them. (In this case to avoid matching user-defined
pragma's that do not have an instance of the private class.)

Separated out from https://dart-review.googlesource.com/c/sdk/+/183640
because of the extra constant in existing expectation files.

Bug: #35763
Bug: #38158
