Migrate more tests from blink repository.

All these tests had <script> tags with additional JS code. All embedded script code is (automatically) concatenated with existing .js files into one .js test file per test.

Simplify sampling rate calculation

Sampling rate is now calculated as total number of samples divided by profiling time in ms. Before the patch the sampling rate was updated once per 100ms which doesn't have any obvious advantage over the simpler method.

Also we are going to get rid of the profile node self and total time calculation in the v8 CPU profiler and only expose profiling start/end time for CpuProfile and number of ticks on each ProfileNode and let clients do all the math should they need it.

Repair test expectations for webkit test.

When adding the new tests in https://codereview.chromium.org/21070002/ the tabs in .js files were automatically replaced with spaces (for presubmit to work).

This replaces the tabs also in a test expectation file for the output to match again.

Adapt test expectations for blink test.

Also after giving it more time, this test times out only on the V8 waterfall under windows. It has an existing expectation for Win Debug, which holds now for all Win.

Turn mark deoptimize on undefined into a proper HPhase.

This patch also removes the implicit recursion on phi operands,
using a loop and a worklist instead, to avoid potential stack
overflows.

Reland initial bits of "Implement correct OS and CC detection."

This adds the OS and CC detection and cleans up the globals.h to
