{- Note [GHCi TupleInfo]
~~~~~~~~~~~~~~~~~~~~~~~~
   This contains the data we need for passing unboxed tuples between
   bytecode and native code

   In general we closely follow the native calling convention that
   GHC uses for unboxed tuples, but we don't use any registers in
   bytecode. All tuple elements are expanded to use a full register
   or a full word on the stack.

   The position of tuple elements that are returned on the stack in
   the native calling convention is unchanged when returning the same
   tuple in bytecode.

   The order of the remaining elements is determined by the register in
   which they would have been returned, rather than by their position in
   the tuple in the Haskell source code. This makes jumping between bytecode
   and native code easier: A map of live registers is enough to convert the
   tuple.

   See GHC.StgToByteCode.layoutTuple for more details.

Note [Field modBreaks_decls]
~~~~~~~~~~~~~~~~~~~~~~
A value of eg ["foo", "bar", "baz"] in a `modBreaks_decls` field means:
The breakpoint is in the function called "baz" that is declared in a `let`
or `where` clause of a declaration called "bar", which itself is declared
in a `let` or `where` clause of the top-level function called "foo".
