Leave promoteds untainted by errors when borrowck fails Previously, when borrowck failed it would taint all promoteds within the MIR body. An attempt to evaluated the promoteds would subsequently fail with spurious "note: erroneous constant used". For example: ```console ... note: erroneous constant used --> tests/ui/borrowck/tainted-promoteds.rs:7:9 | 7 | a = &0 * &1 * &2 * &3; | ^^ note: erroneous constant used --> tests/ui/borrowck/tainted-promoteds.rs:7:14 | 7 | a = &0 * &1 * &2 * &3; | ^^ note: erroneous constant used --> tests/ui/borrowck/tainted-promoteds.rs:7:19 | 7 | a = &0 * &1 * &2 * &3; | ^^ note: erroneous constant used --> tests/ui/borrowck/tainted-promoteds.rs:7:24 | 7 | a = &0 * &1 * &2 * &3; | ^^ ``` Borrowck failure doesn't indicate that there is anything wrong with promoteds. Leave them untainted.
