RFR: JDK-8029007, Check src/share/native/sun/misc code for JNI pending exceptions

[Dan Xu]

Hi Roger,

My macro is a little different from yours, which compares with -1 
instead of NULL. I also see CHECK_EXCEPTION macro. Thanks for adding 
them, which are useful when I cannot decide the pending exception state 
by just using return values.

As for the style, actually I prefer the (!pointer) to (pointer == NULL) 
because it is more concise and also make me avoid the typo like (pointer 
= NULL), which I cannot find from the compilation. Thanks!

-Dan
