Fusion patterns for add-logical/logical-add
This is causing a hang during stage2 of bootstrapping for trunk on power 10. I
tried r12-1019 and it was fine.
Here is one example that happens when configure is running:
. . .
checking for powerpc64le-unknown-linux-gnu-gfortran...
/home/seurer/gcc/git/build/gcc-trunk-bootstrap/./gcc/gfortran
-B/home/seurer/gcc/git/build/gcc-trunk-bootstrap/./gcc/
-B/home/seurer/gcc/git/install/gcc-trunk-bootstrap/powerpc64le-unknown-linux-gnu/bin/

/home/seurer/gcc/git/install/gcc-trunk-bootstrap/powerpc64le-unknown-linux-gnu/sys-include
-fno-checking
checking whether we are using the GNU Fortran compiler...
(and here it hangs)

This should finish almost instantly but never does.
