akhuang requested review of this revision.

When turning on -debug-info-kind=constructor we ran into a "fragment covers
entire variable" error during thinlto. The fragment is currently always
emitted if there is no type size, but sometimes the variable has a
forward declared struct type which doesn't have a size.

This changes the code to get the type size from the GlobalVariable instead.
