Thanks for working it out.  This may be only testcase I know of where
large-function-insns
brings significant regression.

Did you try to experiment with large-stack-frame limits for fortran?  Those hit
quite commonly, perhaps we miss useful inlining here.

I never did really serious tunning on large-function-insns except for quick
check that
increasing it doesn't affect SPEC scores.  But lets fix the underlying branch
prediction
problem and see if we find another testcase supporting the change.
