Bug 24056 – const uninitialized data at module scope is not in TLS

module-level data that is declared const is stored in the global segment, yet is editable from normal static constructors. Either const data should be put into thread local storage, or they should not be editable from static ctors that aren't shared: ```d import std.stdio; import std.concurrency; import core.thread; const void * x; static this() { auto addr = cast(void*) Thread.getThis(); writeln("this thread is ", addr); x = addr; } void main() { writeln("Before spawning thread: ", x); static void foo(Tid owner) { send(owner, 1); } auto tid = spawn(&foo, thisTid); receive((int x) {}); writeln("After spawning thread: ", x); } ``` Output: this thread is 55788EDF3628 Before spawning thread: 55788EDF3628 this thread is 7FC99E404000 After spawning thread: 7FC99E404000
