Java reach: narrower initializer hop, platform boundaries, operator overloads - #1898
Merged

Conversation
…operator arguments in overload choice - impact: a type's static initializer is reached from what initializes the type (JLS 12.4.1: new, a static method call, a static field use); an instance initializer from the type's constructors. No `defines` hop out of an initializer: a lambda or anonymous class written in it is not run by it. - engine: a pinned local of an unstaged platform type takes its declared type; a static call on an unstaged type name is a library boundary rather than an unresolved site. - overload resolution: a numeric/boolean operator expression argument rules out reference-typed overloads.

Java impact / path loop: precision of transitive reach.
Measured on 6 Java subjects (4 tune, 2 held-out), 50 targets each, against a runtime call oracle (test-suite trace). Work in progress: a compiler-resolved oracle is being added next; numbers below are runtime-truth only.

at loadhop: a static initializer is reached from what initializes the type (new, static call, static field use, JLS 12.4.1); an instance initializer from the constructors. Nodefineshop out of an initializer.Cases (red on base, green after, each with a control):
type-initializer-only-from-what-initializes-it,initializer-does-not-run-what-it-defines,platform-receiver-is-a-boundary,overload-by-operator-argument. Java case suite 354/354, engine suite (--oracle) 79/79; 13 goldens re-blessed (onlyambiguous_unknown->boundary_librows).Fixes #1902 (closed by hand on merge: this PR targets the integration branch, so GitHub does not close them).
