RFR(xs): 8147510: [windows] no text locations shown for register info in hs-err file

[Thomas Stüfe]

Hi,

could I please have reviews and a sponsor for this small fix:

Bug: https://bugs.openjdk.java.net/browse/JDK-8147510
Webrev:
http://cr.openjdk.java.net/~stuefe/webrevs/8147510-windows-register-info-print-location/webrev.00/

When we print register to memory info in hs-err file, text addresses are
not resolved on windows like on other platforms:

"RCX=0x000000005efa0000 is an unknown value"

This fix changes this (the same way it is implemented on other platforms):

"RCX=C:\d031900\openjdk\jdk9-hs-rt\output\images\jdk\bin\server\jvm.dll + 0"

Please note that this printout and the code behind it could be improved and
cleaned up a lot. For instance, I know that using an on-stack buffer in
os::find() is not the best implementation here. But I wanted a minimal
change. For the follow-up work, I opened a new bug:
https://bugs.openjdk.java.net/browse/JDK-8147512.

Thanks & Regards, Thomas
