causes ICE (e.g. at -Os -g, -O1 -g, -O2 -g).
The problem is that EXPR_WITH_FILE_LOCATION (STMT_EXPR ()) is passed to
loc_descriptor_from_tree whcih doesn't handle statement expressions and/or
inline functions and aborts.

This is a regression from GCC 3.3.x (where the debug info was not complete
but at least it did not ICE), the testcase is distilled from Linux kernel.

This is a dup of bug 12934 which has a shorter testcase which fails now.
