[PATCH RESEND 1/2] x86: Rename TIF_ADDR32 to TIF_32BIT

[sxwjean]

From: Xiongwei Song <sxwjean@xxxxxxxxx>

In arm64 or powerpc or sparc, the 32 bits process in 64 bits kernel is set
flag TIF_32BIT. However in x86, that flag name is TIF_ADDR32. This patch
makes the flag name in x86 same as other archs.
