Long-failing msvc9 BB related to ImmutableIntervalMap?

It looks like http://google1.osuosl.org:8011/builders/clang-i686-xp-msvc9
has been failing for a long time due to errors in
ImmutableIntervalMap, and we just had someone on #llvm wanting to
build under visual studio hitting the same issue... I can't spot a
change that seems likely to have triggered this, but I knew you'd been
hacking on it Zhongxing, so I thought I'd mention it.

I'll try to set up a Windows + VC 2008 (is it VC 9?) environment to investigate.

I think ddunbar fixed this. Either clang proper or one of the analyses
caught the bug, an unqualified reference to a dependent base class
member.
