[core] Use of null in a field expression

[bagipro]

Class okio.Buffer

    @kotlin.jvm.JvmName(name = "getByte")
    public final byte getByte(long j) {
        okio.Util.checkOffsetAndCount(this.size, j, 1);
        okio.Segment segment = this.head;
        if (segment == null) {
            kotlin.jvm.internal.Intrinsics.throwNpe();
            return null.data[(int) ((((long) null.pos) + j) - -1)]; // <<<

and class com.google.android.gms.internal.ads.zzdo

                if (com.google.android.gms.internal.ads.zzdg.zzo(zzbj.zzcx) || zzto.zzcx.equals("E")) {
                    if (z) {
                        java.lang.String zzas = zzas();
                        if (!com.google.android.gms.internal.ads.zzdg.zzo(zzas)) {
                            zzto.zzcx = zzas;
                        }
                    } else if (z) {
                        zzto.zzcx = null.zzcx; // <<<
                    }
                }

@sergey-wowwow funny but this is exactly what bytecode do (kotlin inlining is weird sometimes).
Anyway, I forbid inlining of null for such cases so code must be compilable now.

Hi @skylot, thanks!

I've detected an error in the fix, class com.google.android.gms.measurement.internal.zzac

    @androidx.annotation.WorkerThread
    private final long zzb(java.lang.String str, java.lang.String[] strArr) {
        android.database.Cursor cursor = null;
        try {
            android.database.Cursor rawQuery = c_().rawQuery(str, strArr);
            if (rawQuery.moveToFirst()) {
                long j = rawQuery.getLong(0);
                if (rawQuery != null) {
                    rawQuery.close();
                }
                return j;
            }
            throw new android.database.sqlite.SQLiteException("Database returned empty set");
        } catch (android.database.sqlite.SQLiteException e) {
            zzr().zzf().zza("Database error", str, e);
            throw e;
        } catch (java.lang.Throwable th) {
            if (0 != 0) { // <<<<<<<
                cursor.close();
            }
            throw th;
        }
    }

Previous code

            if (cursor != null) {

Looks like this issue is same as #920 . Check this description.
