Andy Kaylor fd18a762a0 Enabling the copy-constant-to-alloca optimization in more instances 
Patch by Mohammad Fawaz

This patch allows lifetime calls to be ignored (and later erased) if we
know that the copy-constant-to-alloca optimization is going to happen.
The case that is missed is when the global variable is in a different address
space than the alloca (as shown in the example added to the lit test.)

This used to work before 6da31fa4a6
