@shiltian What do you think about merging this PR to the release branch?

…tem stack size is too big (llvm#81996)

This patch sets the stack size of worker threads to `2 x
KMP_DEFAULT_STKSIZE` (2 x 4MB) for AIX if the system stack size is too
big. Also defines maximum stack size for 32-bit AIX.

(cherry picked from commit 2de269a)
