Leszek Swirski 0ed32e646d [build] Make run_mkgrokdump explicitly dep on run_mksnapshot 
tools/debug_helper:run_mkgrokdump used to only depend on mkgrokdump.
However, the snapshot can change without affecting the mkgrokdump
binary itself. So, if the mkgrokdump binary doesn't change, then
run_mkgrokdump doesn't run, even if the snapshot changed.

This could cause mysterious test failures in incremental builds, in
particular for tests testing the contents of heap-constants-gen.cc.

Now, we make run_mkgrokdump depend on run_mksnapshot_default
directly, so that snapshot updates force an mkgrokdump run.

V8 debug helper

This library is for debugging V8 itself, not debugging JavaScript running within V8. It is designed to be called from a debugger extension running within a native debugger such as WinDbg or LLDB. It can be used on live processes or crash dumps, and cannot assume that all memory is available in a dump.
