code review round 0 for JVM/TI version fix (6849968) and phase assertion (6648438)

[Daniel D. Daugherty]

Greetings,

I have fixes for the following two JVM/TI bugs ready to go:

6648438 4/4 src/share/vm/prims/jvmtiEnv.cpp:457
            assert(phase == JVMTI_PHASE_LIVE,"sanity check")
6849968 3/3 JVMTI tests fails on jdk5.0 with hs14

6849968 fixes a problem where JVM/TI version 1.0 semantics
were not being used when that version was explicitly
requested. I fixed 6648438 because it happened to be in the
same place that I already had to tweak for 6849968. It also
gets rid of an annoying intermittent fastdebug failure.

Here is the webrev URL:

http://cr.openjdk.java.net/~dcubed/batch-20091211-webrev/0/

This webrev is relative to the OpenJDK6 version of the code.
Once approved, these fixes will be pushed to:

- OpenJDK6 (HSX-14-??)
- JDK6-Update train (HSX-16-??)
- OpenJDK7 (HSX-17-??)

Comments, questions and suggestions are always welcome!

Dan
