Yep, 187 seems to be working now.
Not sure about performance, will check this next week when the automatic perf
build arrives.

Okay, testing complete.
The performance delta is less than 1% (0.96% to be exact), but technically the
new solution is still faster than the one before r252781.

r255021 triggers an ICE when 510 is compiled for x86_32 on Haswell:

Whoops. Sorry, 436 belongs to pr83338, even though its ICE message is the same

I don`t know whether anyone reported this to SPEC already, but even if so I
share Richard`s pessimism.
