Refactor utils/compiler/buildbot.py (partly to fix IE bots, partly because it needs it)

This change will:
Disallow bots starting with web-

Support the new naming schema for the ie bots (I explicitly set this
to html|all, but we can change it to a generic identifier if you like)

Introduces a new BuildInfo class that we return from GetBuildInfo
instead of a huge tupple; I want to start passing this around instead
of explicitly giving all the arguments to e.g., TestCompiler, but
currently I don't do it due to our special cases.

Removes the ie sharding todos since we now have an explicit way of passing allong which tests we want based on the name (I am not stating that this is a good solution, but until we have more bots to shard across I think this is better than what we had)

LGTM!

Really nice.

File utils/compiler/buildbot.py (right):

https://codereview.chromium.org/10937024/diff/1/utils/compiler/buildbot.py#ne...
utils/compiler/buildbot.py:222: flags += ['-j1']
We should have a TODO and bug for removing -j1.

https://codereview.chromium.org/10937024/diff/1/utils/compiler/buildbot.py#ne...
utils/compiler/buildbot.py:282: TestStep("dart2js", mode, system, 'dart2js',
runtime, ['dartc',
It is still a problem to use an explicit list of tests. So there should be a
TODO.
