This is a minimalistic script usable for creating packages of gcmole
together with the corresponding Clang. Such packages are used on V8's
infrastructure.

This updates the existing bootstrap.sh script for gcmole to work against
LLVM and Clang version 8.0 releases. This is a follow-up to a previous
change which adapted the gcmole plugin to compile against those same
versions.

After introducing the new pointer-containing Object class in V8 (see
https://docs.google.com/document/d/1_w49sakC1XM1OptjTurBDqO86NE16FH8LwbeUAtrbCo/edit),
gcmole stopped finding errorneous usage of raw pointers in functions that could
trigger GC. This CL modifies the heuristics of the tool to classify Object and
MaybeObject instances as raw pointers, thus giving back the missing warnings.
Updated the gcmole implementation to support modern llvm (tested with llvm 8.0)
for which additional support for MaterializeTemporaryExpr, ExprWithCleanups and
UnaryExprOrTypeTraitExpr was needed.
Basic tests are added to make it harder to introduce such errors without
noticing in the future.
This version gives a lot of false positives when ran on the whole project, see
