./f951 -m31 -O3 vla1.f90 -I ../s390*/libgomp/ -fopenmp -march=z9-109 -mtune=z10
ICEs on 4.4 branch, even in frozz-compiler. The problem seems to be that
substitute_and_fold DCEs some trivially dead stmts and the removal release_defs
the LHS SSA_NAMEs, which are still referenced in various vrp structures.
Then identify_jump_threads is called and ICEs on those already freed ssa-names.
