[Bug tree-optimization/17340] [4.0 Regression] Internal error compiling with -O3

When we die in PRE we have a huge number of SSA names too: 
(gdb) p ssa_names->elements_used 
$8 = 159414 
 
GCC just doesn't scale to such sizes.  I wonder how the function could 
grow this large.  Even at "-O2 -fno-inline" we still ICE in global.c with 
n_basic_blocks == 37278 and max_regno == 49402.
