RFR: 8278053: serviceability/jvmti/vthread/ContStackDepthTest/ContStackDepthTest.java failing in loom repo with Xcomp [v2]

> Please review the following fix.
> 
> When JVM TI puts a thread's state in `interp_only_mode`, thaw takes the slow path and deoptimizes frames as they're thawed in `recurse_thaw_compiled_frame`. However, thawing a deoptimized frame's callee will override the frame's patched pc (to the deopt handler), essentially reverting the deoptimization. This fix patches the deoptimized return address after thawing the callee.
