Description
Windows-only change to disable frame pointer omission with the C++ compiler.[1]  The reason for the change is to get better stack traces in crash logs when a crash occurs in jvm.dll.  Without this change we invariably get only a single jvm.dll frame in the crash log, which makes analysis of Windows field crash reports difficult.

The drawback is that ebp is no longer available as a general register to the C++ compiler.  (Generated code is not affected.)
