0648177ed7 AstGen: avoid multiple dbg_stmt instructions in a row 
This is purely an optimization to emit fewer ZIR instructions.

3389890709 stage2: error return tracing handles ret better 
Sema: insert an error return trace frame when appropriate when analyzing
ret_load. Also optimize the instructions to avoid an unnecessary block
sent to the backends.

AstGen: always emit a dbg_stmt for return expressions, in between the
defer instructions and the return instruction.

This improves the following test case:

```zig
pub fn main() !void {
    return foo();
}

fn foo() !void {
    return error.Bad;
}
```

The error return trace now points to the return token instead of
pointing to the foo() function call, matching stage1.

1a500b9699 Sema: avoid error return traces when possible 
stage2 was adding bogus error return trace frames when an error was not
being returned. This commit makes several improvements:

 * Make a runtime check if necessary to only emit a frame into the error
   return trace when an actual error is returned.
 * Use the `analyzeIsNonErrComptimeOnly` machinery to avoid runtime
   checks when it is compile-time-known that the value is an error, or a
   non-error.
 * Make std.builtin.returnError take a non-optional stack trace pointer.

df8cfb1273 feat: new search placeholder 
This new search placeholder looks much nicer because it allows HTML inside it which
the `placeholder` attribute on `<input>`s doesn't allow.
I tested it for all kinds of cases and it seems to work pretty well.

6354851909 fix: "dialog" -> "modal" 
"Dialog" is the incorrect term here because a dialog is a separate window that still lets you use the app
but a modal is a window where you can't continue using the app until you close it.
