Auto merge of #87875 - asquared31415:generic-lang-items, r=cjgillot
Improve detection of generics on lang items Adds detection for the required generics for all lang items. Many lang items require an exact or minimum amount of generic arguments and if they don't exist, the compiler will ICE. This does not add any additional validation about bounds on generics or any other lang item restrictions. Fixes one of the ICEs in #87573 cc `@FabianWolff`
