Put the LICM of constant GlobalVariables, introduced in r53945, under a
...
command-line option, and disable it by default. It introduced performance
regressions because CodeGen is currently not able to remat such loads.

"Allow LICM to sink or lift loads from constant memory. Also add a test
...
case for this.
This allows instructions like loads from global variables declared to
be constant to be moved out of loops."
