Avoid hashing free type parameters by object/name identity in type
hashing and use traversal-local canonical IDs instead.
This keeps obfuscated field names stable across alpha-renamed generic
signatures (e.g. T vs newT), fixing interface/method mismatches.
The added test case fails without the fix:
> exec garble build
[stderr]
# test/main
YiaBFlNH.go:48: cannot use bT6psGs5O (variable of type *QdwRyqV[aEqmF4M, zpotHfQdnNB]) as E_OKfdHoPH[zpotHfQdnNB] value in return statement: *QdwRyqV[aEqmF4M, zpotHfQdnNB] does not implement E_OKfdHoPH[zpotHfQdnNB] (wrong type for method Redirect)
have Redirect(struct{palTavb zpotHfQdnNB})
want Redirect(struct{g3N8A_R zpotHfQdnNB})
The fix is Paul's; this is rebased on an updated version of typeutil,
and the test is now part of typeparams.txtar and much smaller.
Fixes #991.
