tree-optimization/110506 - bogus non-zero mask in CCP for vector types
get_value_for_expr was blindlessly using TYPE_PRECISION to produce
a mask for vector typed entities which the new tree checking now
catches.
PR tree-optimization/110506
* tree-ssa-ccp.cc (get_value_for_expr): Check for integral
type before relying on TYPE_PRECISION to produce a nonzero mask.
* gcc.dg/pr110506.c: New testcase.
