Bytecode instructions like PUSH_L (push a local variable) contain
an operand that refers to the stack slot. Before this patch, the
operand type was SmallOp (Word16), limiting the maximum stack
offset to 65535 words. This could cause compiler panics in some
cases (See #22888).
This patch changes the operand type for stack offsets from
SmallOp to Op, removing the stack offset limit.
Fixes #22888
(cherry picked from commit 564164ef323a9f2cdeb8c69dcb2cf6df6382de4e)

This fixes #23492. The problem was that we used the real source span
of the field declaration for the generated catch-all case in the
selector function, in particular in the generated call to
`recSelError`, which meant it was included in the HIE output. Using
`generatedSrcSpan` instead means that it is not included.
