x86: Clean up dumpstack_64.c code
The dump_trace() function in dumpstack_64.c is hard to follow.
The test for exception stack is processed differently than the
test for irq stack, and the normal stack is outside completely.
By restructuring this code to have all the stacks determined by
a single function that returns an enum of the following:
STACK_IS_NORMAL
STACK_IS_EXCEPTION
STACK_IS_IRQ
STACK_IS_UNKNOWN
and has the logic of each within a switch statement.
This should make the code much easier to read and understand.
