RFR (L, tedious again, sorry) 8189610: Reconcile jvm.h and all jvm_md.h between java.base and hotspot

[coleen.phillimore at oracle.com]

Summary: removed hotspot version of jvm*h and jni*h files

Mostly used sed to remove prims/jvm.h and move #include "jvm.h" after 
precompiled.h, so if you have repetitive stress wrist issues don't click 
on most of these files.

There were more issues to resolve, however.  The JDK windows jni_md.h 
file defined jint as long and the hotspot windows jni_x86.h as int.  I 
had to choose the jdk version since it's the public version, so there 
are changes to the hotspot files for this. Generally I changed the code 
to use 'int' rather than 'jint' where the surrounding API didn't insist 
on consistently using java types. We should mostly be using C++ types 
within hotspot except in interfaces to native/JNI code.  There are a 
couple of hacks in places where adding multiple jint casts was too painful.

Tested with JPRT and tier2-4 (in progress).
