Fix syntax error in builder_unittests and update broken tests

This patch adds a missing } from [1] which caused a syntax error and
prevented the builders unittests from running properly. With the
syntax error fixed, two test failures were exposed:

1) The "loading steps" test was failing because [1] changed the bot
base path to be hardcoded to "http://build.chromium.org/p/".
2) The "builders.master" test was failing because [1] changed the
bot names to be "chromium.webkit" and "chromium.win" instead of
"dummyurl" and "dummyurl2", respectively.

Remove dead code in RenderBlock::localCaretRect.

As it turns out, every RenderBlock is a RenderBlock.
So this code seems to have been dead since 2009, at least.

This also removes not one, but *two* FIXMEs.

Split compositing/repaint/should-not-repaint-*.html into smaller tests

The original tests each contain multiple tests making the results
hard to read.

Split them into smaller tests and convert them into text based
repaint tests.
