Fix clang updating script to actually track Chrome's (#3806) 
Fix clang updating script to actually update clang based on Chrome's

With this change, clang (llvm-project) will be updated from:
e84b7a5fe230e42b8e6fe451369874a773bf1867
to Chrome's current version:
99ac9ce7016d701b43b8f0c308dc3463da57d983.

This commit fixes two bad bugs:
1. Using the output of a command instead of the return code.
2. Using ! to determine whether the command succeeded ! in bash
will do the same thing for 0 and 1.

These bugs were hidden by OUR_LLVM_REVISION which we traditionally
set to the last commit we rolled back to. If this were a comment
instead of stored as a variable that is not supposed to be used
unless FORCE_OUR_REVISION is set, this bug probably could have
been caught earlier. Instead, the code always used the value
provided by this variable.

Fixes https://github.com/google/oss-fuzz/issues/3805

Use "x86" instead of "i386" for better name recognition. (#2685) 
It seems more people understand x86 than i386, use this term instead.

Mike Aizatsky de6c41a671 [infra] building clang with a single RUN command. 
Each RUN command creates an overlay layer. This results in keeeping all
intermediate files.

By consolidating all work in a single script, the size of base-clang
image is decreased from 3G to 1G.
