arm64: introduce is_a32_task and is_a32_thread (for AArch32 compat)
Based on patch of Andrew Pinski.
This patch introduces is_a32_compat_task and is_a32_thread so it is
easier to say this is a a32 specific thread or a generic compat thread/task.
Corresponding functions are located in <asm/is_compat.h> to avoid mess in
headers.
Some files include both <linux/compat.h> and <asm/compat.h>,
and this is wrong because <linux/compat.h> has <asm/compat.h> already
included. It was fixed too.
