Fixes for a bug in desugaring pattern synonyms matches, introduced
while working on on expanding `do`-blocks in #18324
The `matchWrapper` unecessarily (and incorrectly) filtered out the
default wild patterns in a match. Now the wild pattern alternative is
simply ignored by the pm check as its origin is `Generated`.
The current code now matches the expected semantics according to the language spec.

This hint is outdated, ``Complex Float`` are now specialised,
and the heap space suggestion needs more nuance so it should
be explained in the unboxed/storable array documentation.

When checking if a jump has more than one destination account for the
possibility of some jumps not being representable by a BlockId.
We do so by having isJumpishInstr return a `Maybe BlockId` where Nothing
represents non-BlockId jump destinations.
