Massive SPEC failures on trunk

[Vladimir Sysoev]

Hi, All
There is reproducer for cpu2006/447.dealII attached in archive. I
can't do it smaller than 2 times.

Command line is:

gcc -c -o fe_tools.o -O2 -DSPEC_CPU -Ddeal_II_dimension=3 -g fe_tools.pre.cc

Compiler reports:

fe_tools.cc: In static member function 'static void
FETools::get_projection_matrix(const FiniteElement<dim>&, const
FiniteElement<dim>&, FullMatrix<number>&) [with int dim = 3, number =
double]':
fe_tools.cc:378: error: definition in block 57 does not dominate use in block 59
for SSA_NAME: NMT.3136_606 in statement:
NMT.3136_674 = PHI <NMT.3136_606(59), NMT.3136_692(38)>
PHI argument
NMT.3136_606
for PHI node
NMT.3136_674 = PHI <NMT.3136_606(59), NMT.3136_692(38)>
fe_tools.cc:378: internal compiler error: verify_ssa failed
