kill `isleaftype` #25496

vtjnash · 2018-01-10T19:38:39Z

As discussed in previous issues (listed below), this finishes the deprecation of isleaftype and adds/corrects a number of other type-property queries and their usages (esp. including isbits). This correction also includes a number of changes that makes inference more powerful (by leveraging the removal of isleaftype to return more correct answers, yay!).

Most of the new computations are cached inside a datatype upon construction:

// properties of `parameters`
     uint8_t hasfreetypevars; // majority part of isconcrete computation
+    uint8_t isconcretetype; // where this type can have instances
+    uint8_t isdispatchtuple; // aka isleaftupletype
// properties of `types`
+    uint8_t isbitstype; // relevant query for C-api and type-parameters
+    uint8_t zeroinit; // if one or more fields requires zero-initialization
+    uint8_t isinlinealloc; // if this is allocated inline
// removed attributes
-    int32_t depth; // not a well-defined concept
-    int8_t isleaftype; // already deprecated, now gone

fix #25044
fix #23567
fix #17086
fix #25310

~~This still needs docs from #17086 (comment), and I should go back through and add some tests. But wanted to start by publish the functional changes now.~~

Something went wrong when running your job:

Random moving to the stdlib broke Nanosoldier. I have a fix up, I just need to retune the benchmarks then I'll run Nanosoldier here when that's done.
