no-copy semantics for if expr
```zig
export fn entry() void {
var c = true;
var x = if (c) u8(4) else u32(10);
}
```
```llvm
define void @entry() #2 !dbg !35 {
Entry:
%c = alloca i1, align 1
%x = alloca i32, align 4
store i1 true, i1* %c, align 1, !dbg !44
call void @llvm.dbg.declare(metadata i1* %c, metadata !39, metadata !DIExpression()), !dbg !45
%0 = load i1, i1* %c, align 1, !dbg !46
br i1 %0, label %Then, label %Else, !dbg !46
Then: ; preds = %Entry
br label %EndIf, !dbg !47
