More cleanup: use waitForComposite() in buffer-offscreen-test.html
Replace GetBufferDataDest with ArrayBufferData

The typedef for (ArrayBuffer or ArrayBufferView) is now
part of WebIDL:
http://heycam.github.io/webidl/#common-ArrayBufferData

It seems the IDL file was a little out of date to, so this
is the generated file from tip-of-tree.
Modify test runner to dump translated shaders

This change adds a test runner feature that dumps translated shaders
while running glsl conformance tests.

For each test, a summary json file is created which has all the
information like original shaders, test description, whether shader
should compile and path to translated shaders.

For all the glsl test shaders that compile successfully, translated
shaders are dumped to separate files so that it can be fed directly
to the compiler.

All the translated shader and summary files are compressed into a
tar.gz at the time of finishing tests.

New test runner command line option --dump_shaders is added and it
needs to be passed for dumping translated shaders.

Add test for stressing TypedArray garbage collection

Test that throw-away Float32Arrays used to update WebGL buffer data get
garbage collected reasonably instead of inflating the renderer memory
use.

Ternary Operators in Global Initializers

Add a test to verify that ternary operators can be used in global initializers.

Fragment shaders are of the form:
  precision mediump float;
  $(type) green = $(green);
  $(type) black = $(black);
  $(type) var = (true) ? green : black;
  void main() {
      gl_FragColor = $(asVec4);
  }

In order to pass, program should successfully link and output green.

Rename 'finishTest' to 'finishIndividualTest'

This change renames 'finishTest' to 'finishIndividualTest' to avoid
any confusion with already existing 'finish' handler. And also
added comment describing finishIndividualTest.
