pstef 7b8e56a144 EE/FPU: give mode 3 the multiplier predicate's boundary term ...

The predicate was a Cmtst against a mask parked in d10, which can
express the Booth term and nothing else, so iFPUd came back one ULP high
wherever the boundary term at the truncation column was the deciding one
-- a class the interpreter models. Building the predicate in GPRs
instead admits both terms, and turns the old shape's implicit tail test,
which worked only because FPUFPCR holds round-toward-zero, into an
explicit one.

Nothing reads d10 after that, so it leaves the reserved list and the
allocator has its callee-saved slot back.
