Blacklist xlc 32-bit inlining.

nmisch · nmisch · commit 76cf5f1956ce · 2015-07-29T22:53:09.000-04:00
Per a suggestion from Tom Lane. Back-patch to 9.0 (all supported versions). While only 9.4 and up have code known to elicit this compiler bug, we were disabling inlining by accident until commit 43d89a2.
