Fine with me, done in r211190.

I thought that this wasn't really needed since there is already
a test for the indirect call sequence; however, after adding the
test I noticed that the generated code is a bit less efficient
than it might be; this should improve with another patch to
improve TOC loading I'm planning to commit soon :-)
