RFR(XXS): 8008391: Incorrect metadata for event based tracing

[Erik Gahlin]

Hi,

Could you please review these small metadata changes for the event 
tracing framework:

- Promotion Failed -> objectCount has the datatype BYTES64, which 
implies that it is a size. It is not, and the type should be an unsigned 
long.

- Thread Park, Java Monitor Enter and Java Monitor wait should have 
relational ids, so it's possible to see that the information is related 
("java/monitor/address")

- The field "caller" in ExecuteVMOperation should not have a TO field 
but a FROM field, indicating from which thread the "transition" came from.

The reason the review for 8007150 is handled seperately is because it 
modifies the structure of the data,  while these changes are strictly 
cosmetical.
