4d613f404f use dbghelp.dll to generate crash dump file on Windows XP and later
The dump is written to the directory specified via the avian.crash.dir
system property if that property is set and is not written otherwise.

6a5116e7a7 implement primitive heap dump facility for memory profiling, accessible via Runtime.dumpHeap
The proper way to do this is to implement a subset of JVMTI, but this
will do the job for now.

c8cc7d931b maintain a table to look up methods called via JNI
This simplifies the JNI implementation for looking up methods.  It also
fixes a bug where an applications calls GetStaticMethodID with class A
and then calls CallStatic<Type>Method with class B which extends A.  The
old code would look in the wrong method table and thus call the wrong
method.

8e5ce11047 refactor memory management code
We now support immortal objects, which the GC will scan for references
but not consider for collection.  On x86_64, we allocate JIT code memory
via mmap, which lets us map memory into the bottom 2GB of the address
space, ensuring that 32-bit relative jumps and calls work.
