I've added location to ast::Unary. We also generate implicit references/dereferences during type-checking, which also needed locations in the node_interner, or else we'd crash when trying to access the location when creating the corresponding ast::Unary |

Description
Problem*
Resolves #2412
Summary*
For normal binary expression we call
FunctionContext::insert_binarywhich inserts a binary instruction and checks if truncation is needed.However, for unary minus we directly call into the
FunctionBuilderwhich skips this check -- this PR replaces that function call with a call toFunctionContext::insert_binary.The
locationargument inFunctionContext::insert_binaryis also made optional sinceast::Unarydoesn't have a location and it would be a bit of a pain to add it, because in mono we sometimes generate unary expressions on the fly.Documentation
This PR requires documentation updates when merged.
