<pre>We could potentially store initializers and attached metadata in a bitcode
block for global variables much like the existing block type for functions.
This would allow us to load global variable definitions lazily, which could
potentially improve lazy loading performance and allow us to remove the global
constants block.
However, there is a possibility that this would reduce data sharing, which
could regress overall performance. We should investigate this and figure out
whether it would be beneficial overall.</pre>
