Paul Mackerras f40842d9b2 tests/fpu: Test FPU unavailable interrupt following a load
This adds a load before a floating-point load which should generate a
floating-point unavailable interrupt, to test for the bug where
unavailability interrupts can get dropped while loadstore1 is
executing instructions.
