[compiler] Preserve Create effects, guarantee effects initialize once (#33558)

Ensures that effects are well-formed with respect to the rules:
* For a given instruction, each place is only initialized once (w one of
Create, CreateFrom, Assign)
* Ensures that Alias targets are already initialized within the same
instruction (should have a Create before them)
* Preserves Create and similar instructions
* Avoids duplicate instructions when inferring effects of function
expressions
