Add __builtin_ia32_interrupt_data
The interrupt and exception handlers are called by x86 processors. X86
hardware pushes information onto stack and calls the handler. We need
a builtin function to access interrupt or exception data from the
interrupt and exception handlers which are void function without
arguments. This patch adds __builtin_ia32_interrupt_data so that
interrupt or exception data can be retrieved from the interrupt and
exception handlers.
