Please review this small fix for fixing a warning from our internal code
analysis tool. The problem is that on 64-bit platforms, the uintptr_t is
64-bit and we tried to return it as a jint which is always 32-bit.
A simple fix is to add an assert to make sure the value is <= max_jint
before returning it as a jint.

bug: https://bugs.openjdk.java.net/browse/JDK-8033566
      (internal, below is the details)
Expecting value of JNI primitive type jint in return at line 536 of
jdk8-b128/src/hotspot/src/share/vm/runtime/frame.cpp in function
frame::interpreter_frame_expression_stack_size()
