Stop leaking file descriptors.
...
After the open+fstat optimization, files were already opened for FileManager::getBufferForFile() and we closed them after reading them.
The problem was that when -working-directory was passed, the code path that actually reuses & closes the already opened file descriptor
was not followed.

Implement a hack intended to allow Clang to parse libstdc++ 4.5's
...
headers, which use C++0x generalized initializer lists. Per PR7069, it
appears that the only use is as the return type of a function, so this
commit enables this extension just in that narrow case. If it's enough
for libstdc++ 4.5, or if it can be trivially extended to work with
libstdc++ 4.5, we'll keep it. Otherwise, or if this breaks anything,
we'll revert and wait for the real feature.

of just in one place up front.
