Workaround bug in llvm-gcc

llvm-gcc (shipped in Apple XCode 4.1.1 as the default compiler or in
the 2.9 release of LLVM) performs an invalid optimization which
unifies the empty_region and the bad_region structures because they
have the same content.

A bugreport has been filed against Apple Developers Tool for this
issue. This commit works around this bug by making one of the two
structures volatile, so that it cannot be merged.

Fixes region-contains-test.
