05849e8c2f Use fewer delayed bugs. 
For some cases where it's clear that an error has already occurred,
e.g.:
- there's a comment stating exactly that, or
- things like HIR lowering, where we are lowering an error kind

The commit also tweaks some comments around delayed bug sites.

df116ec246 Migrate memory overlap check from validator to lint 
The check attempts to identify potential undefined behaviour, rather
than whether MIR is well-formed. It belongs in the lint not validator.

2beabbbf6f Rename adjustment::PointerCast and variants using it to PointerCoercion 
It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related
casts, when in reality their just used to share a some enum variants. Make it clear there these
are only coercion to make it clear why only some pointer related "casts" are in the enum.

f16d2b1629 Start node has no immediate dominator 
Change the immediate_dominator return type to Option, and use None to
indicate that node has no immediate dominator.

Also fix the issue where the start node would be returned as its own
immediate dominator.
