SDK 8.2, 8.3, 8.4 - two critical regressions in one: compile time lookup is broken again + performance degradation of all applications at runtime

class C {
    static function f() as Void {}
}

class D {
    function g() as Void {
        C.f();
    }
}

Compiler options are "-w -l 3 -O 3".

Assembler code for 8.0, 8.2.3, 8.3.0, 8.4.0:

globals/D/g:
    argc 1
    getselfv C
    getsv f
    invokemz
    popv
    return
globals/D/g_func_end:

Assembler code for SDK 7, and 8.1.1:

globals/D/g:
    argc 1
    getmv globals C
    getsv f
    invokemz
    popv
    return
globals/D/g_func_end:

I have already reported it, and it was fixed in 8.1.1, but it is broken again: https://forums.garmin.com/developer/connect-iq/i/bug-reports/sdk-8-2-3-member-lookup-is-broken-both-in-type-checker-and-compiler.

At best, it is a HUGE performance regression, since compile-time lookups are replaced with runtime lookups in almost every line of Monkey C code.
