* Basic IR support for `static const` globals Our strategy for lowering global *variables* can fall back to putting their initialization into a function, but that isn't really appropriate for global constants (it also isn't appropriate for arrays, but we'll need to deal with that seaprately). This change adds a distinct case for global constants (rather than treating them as variables), and forces the emission logic to always emit them as a single expression. Doing this makes assumptions about how the IR for these constants gets emitted (and what optimziations might do to it). In order to make things work, I had to switch the handling of initializer-list expressions to not be lowered via temporaries and mutation (since that isn't a good fit for reverting to a single expression). I've added a single test case to ensure that this works in the simplest scenario. My next priority will be to see if this unblocks my work in Falcor. * Fixup: bug fixes
