  Suppress returning larger CXX records in mem on PlayStation (#161732)

In commit e8a486ea9789, a change was made so that certain 256-bit and
512-bit CXX records would be returned in memory, fixing a violation of
the x86-64 psABI (where they had been incorrectly returned in AVX
registers). For compatibility reasons, we want to suppress that ABI-fix
on PlayStation. This commit suppresses that change for PlayStation, and
updates the test to include checking the 512-bit case.
