4.3 is also broken.  Using the simpler test case in PR43732 and a collection of
cross-compilers to mips-unknown-linux I see:

gcc-4.1.2: -O2 only: ok; -O2 -ffixed-23: ok
gcc-4.2.4: -O2 only: ok; -O2 -ffixed-23: ok
gcc-4.3.x: -O2 only: ok; -O2 -ffixed-23: bug (for x in 0..4)
gcc-4.4.x: -O2 only: bug; -O2 -ffixed-23: bug (x=0, x=3)
gcc-4.5.0: -O2 only: bug; -O2 -ffixed-23: bug

So -ffixed- broke between 4.2 and 4.3, and global register variables broke
between 4.3 and 4.4.
