Eric Christopher ea4b6dfd8f Rework constant expr and array handling for objectsize instcombining. ...

Fix bugs where we would compute out of bounds as in bounds, and where
we couldn't know that the linker could override the size of an array.

Add a few new testcases, change existing testcase to use a private
global array instead of extern.
