f6ca2c1d8f Remove the Dart 1 tests.
This deletes:

tests/co19
tests/corelib
tests/html
tests/isolate
tests/language
tests/lib

It does not delete tests/standalone because apparently there are tests
in there that are not in standalone_2. (I assume they were added after
the test migration. I don't know why they were added there.)

I have tried to remove references to the old tests from various scripts
and tools but may have missed some. (As you can imagine, grepping for
"lib" does not have the best signal-to-noise ratio.)

"It was a pleasure to burn. It was a special pleasure to see things
eaten, to see things blackened and changed. With the brass nozzle in his
fists, with this great python spitting its venomous kerosene upon the
world, the blood pounded in his head, and his hands were the hands of
some amazing conductor playing all the symphonies of blazing and burning
to bring down the tatters and charcoal ruins of history."

- Ray Bradbury, Fahrenheit 451

ccfafee023 Make list_files.py and list_dart_files.py return absolute paths for GN
This makes doing an SDK build in the Fuchsia tree easier.

The previous attempt at this change failed in gyp builds targeting xcode.
They failed because input lists for actions of the same target (e.g. the
actions for dartanalyzer) are merged and de-duped when the lists contain
relative paths, but merged and *not* de-duped when the lists contain
absolute paths. gyp rejects xcode files that it generated itself
when they contain duplicate entries.

This CL works around that bug, by using absolute paths in the GN build
and keeping relative paths in the gyp build.

427f760c91 Build lib/_internal/analysis_summary during SDK build.
We cannot commit this CL right now, because we will attempt to use
these summaries by default, and they are incomplete yet. But I wanted
to see how to add something to the build process, and we might do
changes to make using SDK summaries optional initiallyand then commit
this CL.
