While fuzzing I noticed we would now ICE in two places when encountering an empty or filled #![rustc_never_type_options()] attr:

compiler/rustc_passes/src/check_attr.rs:160:33: builtin attribute "rustc_never_type_options" not handled by CheckAttrVisitor
compiler/rustc_attr_parsing/src/validate_attr.rs:42:17: assertion failed: lint_attrs.contains(name)

So remove these two entries after which we will just error with error: cannot find attribute

While fuzzing I noticed we would now ICE in two places when encountering an empty or filled #![rustc_never_type_options()] attr:
compiler/rustc_passes/src/check_attr.rs:160:33: builtin attribute "rustc_never_type_options" not handled by CheckAttrVisitor

compiler/rustc_attr_parsing/src/validate_attr.rs:42:17: assertion failed: lint_attrs.contains(name)
So remove these two entries after which we will just error with error: cannot find attribute

While fuzzing I noticed we would now ICE in two places when encountering an empty or filled #![rustc_never_type_options()] attr:
compiler/rustc_passes/src/check_attr.rs:160:33: builtin attribute "rustc_never_type_options" not handled by CheckAttrVisitor

compiler/rustc_attr_parsing/src/validate_attr.rs:42:17: assertion failed: lint_attrs.contains(name)
So remove these two entries after which we will just error with error: cannot find attribute
