Fix deferring global array initialization The initial implementation of DeferGlobalInitializers did not take HLSL corner cases into account. In particular, in case there was a const-qualified array variable with an initializer that contained elements that weren't constant folded, initialization would not be deferred and the global scope of HLSL output would contain a call to angle_construct_into_*(). On the other hand, deferring global initializers was also done in cases where it wasn't necessary. Initializers of non-const qualified array variables that could be written as HLSL literals by HLSL output were unnecessarily deferred. This patch fixes both of these issues: Now all global initializers are potential candidates for deferral instead of just those where the symbol has the EvqGlobal qualifier, and initializers that are constructors taking only constant unions as parameters are not unnecessarily deferred.
