Should fix #14. Generate #%require at namespace base phase for top-level expressions

[shhyou]

After this patch, the test case posted by @florence in #14 passes. The following program also runs, but I didn't run it in DrRacket.

#lang racket
(require errortrace)
(require (for-template phc-adt))

[mflatt]

LGTM

@shhyou did you accidentally close the PR?

[shhyou]

I thought the issue is already fixed when reading the commit history at some point, but could be that I just confused myself.

I can look into this again tomorrow.

[sorawee]

I can confirm that it is not fixed. Running the test that you adds fails with #%require: unbound identifier;

[shhyou]

Thanks for the heads up. I forgot about this and indeed the issue is unfixed. I've updated the pull request.

[sorawee]

Is it possible to get this merged by the 7.9 release?

@sorawee branch day has already happened (yesterday) but I think it is okay if @mflatt still is happy with the commit.
