Fix an infinite loop in the Linker and a few other assorted link problems.

Patch contributed by Scott Michel. Thanks, Scott!

potentially some system calls/exception handling from working.  TOS must always
link to previous frame.  This is a short term workaround until alloca scheme is
reworked.

Added X86 specific nodes X86ISD::FMAX, X86ISD::FMIN instead.
