Tyson Andre df0fa5b178 Clean up remaining opcodes for foreach([] as $x) 
Previously, two useless FE_RESET_R and FE_FREE would be left over whether the empty array
was from a literal, a variable, or a class constant.

This doesn't pick up the RESET_RW case due to a weakness in our "may throw"
modeling. (for foreach by reference).
