New LLVM backend cannot compile procedures with type

[ThisDevDane]

Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• Operating System: Win 10 x64 Version 1909
• Odin version/Commit: 732c745

Expected Behavior

For the example to compile using --llvm-api.
This seems to be related to when declaring functions like name : delegate_type : proc()

Current Behavior

It fails to compile with --llvm-api

Failure Information (for bugs)

When compiling the example with --llvm-api following error gets raised;

[Build Debug]
odin build ./generator_v2 --out=odin-imgui-gen.exe --llvm-api --debug
e:\odin\src\llvm_backend.cpp(2359): Assertion Failure: `(p->type_expr)->kind == GB_JOIN2(Ast_, ProcType)` expected 'procedure type' got 'selector expression'
make: *** [Makefile:27: build_debug] Error -2147483645

Steps to Reproduce

1. Compile the following code with --llvm-api

package main

import "core:fmt"
import "core:os"
import "core:log"
import "core:odin/ast"
import "core:odin/tokenizer"
import "core:odin/parser"

main :: proc() {
    predefined_file := ast.File {
        fullpath = "imgui_predefined.odin"
    };
    src, _ := os.read_entire_file(predefined_file.fullpath);
    predefined_file.src = src;

    err_log : parser.Error_Handler : proc(pos: tokenizer.Pos, msg: string, args: ..any) {
        log.errorf("%s(%d:%d): ", pos.file, pos.line, pos.column);
        log.errorf(msg, ..args);
    }

    warn_log : parser.Warning_Handler : proc(pos: tokenizer.Pos, msg: string, args: ..any) {
        log.warnf("%s(%d:%d): ", pos.file, pos.line, pos.column);
        log.warnf(msg, ..args);
    }

    p := parser.Parser {
        err  = err_log,
        warn = warn_log,
    };

    ok := parser.parse_file(&p, &predefined_file);
    if ok == false || p.error_count > 0 {
        log.error("FAILED TO PARSE 'predefined_imgui.odin'");
        os.exit(1);
    }

    fmt.println("DONE");
}
