Work around gcc 4.6.0 bug that breaks WAL replay. ReadRecord's habit of using both direct references to tmpRecPtr and references to *RecPtr (which is pointing at tmpRecPtr) triggers an optimization bug in gcc 4.6.0, which apparently has forgotten about aliasing rules. Avoid the compiler bug, and make the code more readable to boot, by getting rid of the direct references. Improve the comments while at it.
Back-patch to all supported versions, in case they get built with 4.6.0.
