Subject: [committed] Fix problem handling return value aggregates on PA
Authentication-results: sourceware.org; auth=none

The attached problem fixes a regression in handling DFmode aggregatesin pa_function_value.Sometimes, an aggregrate with a single DFmode field could not behandled by the existing codewhich used a BLKmode parallel. We can just use a register when theaggregate fits exactly in a

single or double word.  This avoids an ICE in store_field.

Tested on hppa2.0w-hp-hpux11.11, hppa-unknown-linux-gnu and hppa64-hp-hpux11.11. Committed

to trunk and 4.9 branch.
