config/mmix/mmix.h (NO_FUNCTION_CSE): Define to 1.

Browse Source 
The tests gcc.dg/tree-ssa/loop-1.c and gcc.dg/weak/typeof-2.c
assume this setting and are as a consequence riddled with
exceptions for targets that actually do yield better code when
calling through a register rather than repeatedly the same
symbol.  Nonetheless, defining it makes sense for MMIX.

(Even better IMHO, this macro shouldn't exist and instead rtx
costs be used or perhaps just a target-specific default of
flag_no_function_cse.)
