tree-ssa-dce: Fix calloc handling [PR118224]
As reported by Dimitar, this should have been a multiplication, but wasn't
caught because in the test (~(__SIZE_TYPE__) 0) / 2 is the largest accepted
size and so adding 3 to it also resulted in "overflow".
The following patch adds one subtest to really verify it is a multiplication
and fixes the operation.

* tree-ssa-dce.cc (is_removable_allocation_p): Multiply a1 by a2
instead of adding it.
* gcc.dg/pr118224.c: New test.
