[PATCH 2/2] Fix uninitialised fields in aix_thread_variables structure.

[Aditya Vidyadhar Kamath <akamath996@gmail.com>]

From: Aditya Vidyadhar Kamath <aditya.kamath1@ibm.com>

The fields in aix_thread_variables structure were never initialised.

So we initialise them and also change to bool since they are
purely flags.

This patch updates all assignment sites to use true or false
accordingly.
