So basically what we have is that gcc miscompiles itself somewhere in the code
where one of those ~7000 gcc_assert is used. The next step is to identify which
one of them triggers this bad behaviour (bisecting not in the svn revisions,
but in gcc source files by flipping the use of __builtin_unreachable-based vs.
ordinary gcc_assert implementations) and extract a reduced testcase showing
__builtin_unreachable failure.
