First, for internal variables, they are always global, so use the global AS by default unless specified otherwise. We can't really use `0` as a default like we do now because that has an actual meaning on some targets, so we really need specified vs unspecified, so I used `std::optional` which is already used in many places in OMPIRBuilder. Second, for the critical lock variable, add an addrspace cast if needed. Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
