Test case showing broken capture of this

When creating a lambda function in a template member function, when capturing
this using [=], this is not captured correctly when the lambda only calls
another template member function reusing the outer template argument.

Qualifying the call with this or not passing on the outer template argument
solves the issue.

In the attached code, I expect this to be captured in all 4 cases, but the
"broken" captures null resulting in the print out:

./test
(nil)
0x7fff1354f2af
0x7fff1354f2af
0x7fff1354f2af

GDB shows the same - this has been captured but with null as value.

clang 3.2 captures this as expected.
