6ab61037f3 Add gdb macro to find assertion scopes on the stack. 
This is how it would look like.

e063b7118c [gdb] Define print functions used by gdb macros in the top level namespace to make them always be available. 
This should fix the following errors that sometimes appear when using V8 gdb macros:
  Cannot evaluate function -- may be inlined
or
  No symbol "xxx" in namespace "v8::internal".

9386b861fd Special printing for type feedback vectors. 
Gdb macro jfv on an object will print it as a feedback vector.
Printouts look like this:
