RFR: 8324630: C1: Canonicalizer::do_LookupSwitch doesn't break the loop when the successor is found

[Denghui Dong]

Hi,

Please review the small change that breaks the loop in Canonicalizer::do_LookupSwitch if the successor is found.

The keys of LookupSwitch are sorted, so there is no need to continue the loop once matched.

Thanks.
