Description:
* This patch tells the Go frontend to insert explicit guards (check for nil ->
panic) for AIX since relying on a fault does not work on AIX for page 0.
Tests:
* AIX: Build: SUCCESS
- build made by means of gmake.
ChangeLog:
* go-lang.c (go_langhook_init): Handle AIX case for nil_check_size_threshold.
