jameysharp opened PR #5706 from cprop-extend to main:

Also move these optimization rules to cprop.isle; it's where all the other similar rules are.

Like the other cprop rules, these can subsume any other rules. We can't do better than reducing an expression to a constant.

The new i64_sextend_imm64 and u64_uextend_imm64 constructors are useful helpers to clean up other code. I applied them to imm64_icmp while I was here, as well as using the existing ty_mask helper to clean up imm64_masked.
