sparse conditional constant propagation can discover optimization opportunities that cannot be found by just combining constant folding and constant propagation and dead code elimination separately.

Congratulations on opening your first change. Thank you for your contribution!

Next steps:
A maintainer will review your change and provide feedback. See
https://go.dev/doc/contribute#review for more info and tips to get your
patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be
surprising to people new to the project. The careful, iterative review process
is our way of helping mentor contributors and ensuring that their contributions
have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which
little code gets reviewed or merged. If a reviewer responds with a comment like
R=go1.11 or adds a tag like "wait-release", it means that this CL will be
reviewed as part of the next development cycle. See https://go.dev/s/release
for more details.

fix crash bug
22954f3 
The crash happens when performing sccp after phiopt.

b28: ← b26 b27
v107 (115) = Phi <*ir.Name> v106 v43 (n[*ir.Name])
v108 (115) = Copy <bool> v105 (ok[bool])
If v108 → b30 b29 (115)

When fistly processes edge b26->b28, all values of b28 is evaluated, but
v108 is not visited because v105 is never possibleConst, later during
propagate(b28), sccp founds v108 is Top, and it ignores further control
flows, this leads to a crash, actually v108 should be Bottom and all of
b28 successors should be append to worklist.

I removed fast fail in visitValue to always evaluate such case and added
a comment to reflect this.(Another approach is to check such case in
possibleConst, which is relatively complex)
