Andrew Boie 89ec552be9 x86: iamcu: fix exception NANO_ESF parameter ... On SysV ABI, the NANO_ESF parameter is passed in via the stack. For IAMCU, this is instead expected to be in EAX. _ExcEnter is currently using EAX to stash the return address of the calling stub while it does a stack switch. Change it to use ECX for this purpose, and if we are running with IAMCU place the parameter in EAX instead of pushing it. The output of the fault handler has been cleaned up a bit and it now also includes the code segment.
