RFR (XS): 8044071: Print format/argument warnings

[Mikael Vidstedt]

Please review the below change which addresses a number of print 
format/argument mismatches when compiling linux/sparc using gcc.

Bug: https://bugs.openjdk.java.net/browse/JDK-8044071
Webrev: http://cr.openjdk.java.net/~mikael/webrevs/8044071/webrev.00/webrev/

Most of these are straightforward changes to INTPTR_FORMAT & adding p2i. 
A couple of changes worth bringing up:

* nativeInst_sparc.cpp

I changed the format of the offset in mov related prints (two 
occurrences) to %d, since it's really a signed decimal int. This will 
hopefully reduce confusion when the offset is negative, where previously 
it would have looked like a relatively large positive offset.

* macroAssembler_sparc.cpp

The new code is in line with other similar patterns in the same file, 
but the ugly cast should IMHO really be rewritten to cast through a 
union. RFE?

Cheers,
Mikael
