 Fix for static constructor bug

+The reason why static constructors don't get executed (sometimes in 
+second domain) is because our shared runtime invoke code generation, 
+before it generated runtime_invoke per method and class. This caused 
+a lot of code that was equal to be compiled therefore we changed this 
+behavior into caching on signature instead, sadly this caused some 
+side effects:
+
+1. Some classes are still dependent on the method, like string and 
+value type methods
+
+2. The class in the cached method (cached by signature) was set to 
+the class of the first method that was cached (by signature), so when 
+compiling this method the class was initialized (in 
+mono_jit_compile_method) but instead of initializing the runtime 
+invoke method class we initialized the first called method cached 
+class again (and sometimes as in this bug, the wrong class in the 
+wrong order) and this caused deadlocks in the class init 
+functionality.
+
+So, the "Fix for static constructor bug" patch changes the behavior 
+into:
+
+1. Signatures that are cached are now cached in object not the class 
+of the first method called.
+2. Value type and string helpers are not cached at all (we should fix 
+this later)
+3. We initialize the correct class in mono_jit_runtime_invoke because 
+mono_jit_compile_method may just initialize system object again 
+(mono_runtime_class_init has functionality to detect if a class is 
+initialized or not)
+
+ugh.
