x86/asm/entry/64: Rename THREAD_INFO() to ASM_THREAD_INFO()
The THREAD_INFO() macro has a somewhat confusingly generic name, defined in a generic .h C header file. It also does not make it clear that it constructs a memory operand for use in assembly code. Rename it to ASM_THREAD_INFO() to make it all glaringly obvious on first glance.
