GCMole mistakenly thought that GC guards such as DisallowHeapAllocation
covered the whole scope of the function they are declared in. This CL
fixes the false negatives and adds appropriate testing.

GCMole now comes with the long forgotten use-after-free detection
enabled by default. The CL also improves error logging when test
expectations mismatch with the actual output and updates the hash
of GCMole to be used with the newly built version with enabled UAF
detection.
The CL also contains an ignore for isolate.cc due to inability to
fix a warning there and fixes a couple of UAF warnings.

This CL ensures we care only about our internal pointer types and not
about raw C++ pointers, because normally special care is taken when
storing raw pointers to the managed heap. Furthermore, checking for raw
pointers produces too many false positives in the dead variable
analysis.

Since this produces a few false positives, also implemented a whitelist
mechanism to not report them.
Also, add a couple of tests and implemented automated testing against
test-expectations file.
