stage2: field type expressions support referencing locals The big change in this commit is making `semaDecl` resolve the fields if the Decl ends up being a struct or union. It needs to do this while the `Sema` is still in scope, because it will have the resolved AIR instructions that the field type expressions possibly reference. We do this after the decl is populated and set to `complete` so that a `Decl` may reference itself. Everything else is fixes and improvements to make the test suite pass again after making this change. * New AIR instruction: `ptr_elem_ptr` - Implemented for LLVM backend * New Type tag: `type_info` which represents `std.builtin.TypeInfo`. It is used by AstGen for the operand type of `@Type`. * ZIR instruction `set_float_mode` uses `coerced_ty` to avoid superfluous `as` instruction on operand. * ZIR instruction `Type` uses `coerced_ty` to properly handle result location type of operand. * Fix two instances of `enum_nonexhaustive` Value Tag not handled properly - it should generally be handled the same as `enum_full`. * Fix struct and union field resolution not copying Type and Value objects into its Decl arena. * Fix enum tag value resolution discarding the ZIR=>AIR instruction map for the child Sema, when they still needed to be accessed. * Fix `zirResolveInferredAlloc` use-after-free in the AIR instructions data array. * Fix `elemPtrArray` not respecting const/mutable attribute of pointer in the result type. * Fix LLVM backend crashing when `updateDeclExports` is called before `updateDecl`/`updateFunc` (which is, according to the API, perfectly legal for the frontend to do). * Fix LLVM backend handling element pointer of pointer-to-array. It needed another index in the GEP otherwise LLVM saw the wrong type. * Fix LLVM test cases not returning 0 from main, causing test failures. Fixes a regression introduced in 6a5094872f10acc629543cc7f10533b438d0283a. * Implement comptime shift-right. * Implement `@Type` for integers and `@TypeInfo` for integers. * Implement union initialization syntax. * Implement `zirFieldType` for unions. * Implement `elemPtrArray` for a runtime-known operand. * Make `zirLog2IntType` support RHS of shift being `comptime_int`. In this case it returns `comptime_int`. The motivating test case for this commit was originally: ```zig test "example" { var l: List(10) = undefined; l.array[1] = 1; } fn List(comptime L: usize) type { var T = u8; return struct { array: [L]T, }; } ``` However I changed it to: ```zig test "example" { var l: List = undefined; l.array[1] = 1; } const List = blk: { const T = [10]u8; break :blk struct { array: T, }; }; ``` Which ended up being a similar, smaller problem. The former test case will require a similar solution in the implementation of comptime function calls - checking if the result of the function call is a struct or union, and using the child `Sema` before it is destroyed to resolve the fields.
