x86: asm linkage - introduce GLOBAL macro



If the code is time critical and this entry is called
from other places we use ENTRY to have it globally defined
and especially aligned.

Contrary we have some snippets which are size
critical. So we use plane ".globl name; name:"
directive. Introduce GLOBAL macro for this.
