[Interpreter] Transform StrictEquality with null/undefined to special bytecodes. Transform LdaNull/LdaUndefined followed by StrictEquality to TestNull/TestUndefined. This would avoid a call to the compare IC. In the bytecode-graph builder these are mapped to StrictEqual javascript operator. When reducing this operator, we already optimize the cases for null/undefined. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2554723004 Cr-Commit-Position: refs/heads/master@{#41768}
