Rollup merge of #130235 - compiler-errors:nested-if, r=michaelwoerister

Browse source 
Simplify some nested `if` statements

Applies some but not all instances of `clippy::collapsible_if`. Some ended up looking worse afterwards, though, so I left those out. Also applies instances of `clippy::collapsible_else_if`

Review with whitespace disabled please.
