hppa: Fix (plus (plus (mult (a) (mem_shadd_constant)) (b)) (c)) optimization
The constant C must be an integral multiple of the shift value in
the above optimization. Non integral values can occur evaluating
IMAGPART_EXPR when the shadd constant is 8 and we have SFmode.

* config/pa/pa.cc (hppa_legitimize_address): Add check to
ensure constant is an integral multiple of shift the value.
