Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.

All of these values are derived from the self samples count and there is no need to evaluate them in v8 when clients can do that when needed on their side.

Also added unsigned GetHitCount() which should be used instead of double GetSelfSamplesCount(). I'm going to deprecate the latter one once Blink has switched to GetHitCount.

Port r16114 (2d1bf399)

Original commit message:
This patch is to enhance the source code line information for profiler.

For the Hydrogen compilation, most of the source code line information
is not copied from the HInstruction the to corresponding LInstruction.

This patch defines one PositionBits field for LInstruction and copies the
sorce code position value from the HInstruction.

When Generating the native code, we use RecordPosition(..) function to
write LInstruction's position value to position recorder.

This simple change moves the Deoptimize call into the Deopt table
where it belongs, and shortens the inline map-check.

Gives a surprisingly large performance gain, around 4% on Octane.

For the MIPS platform, I did not touch because I have no devices
to verify the modification on it.

This change provides an API for the embedder to tell CPU profiler if it is idle or busy with some task. This way we can discriminate between idle time and some native code execution.

Port r16098 (328ff5f7)

Original commit message:
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.

This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.

The test runner can now run a class of tests (flaky|non-flaky|all). All tests are in the non-flaky class that are not marked as FLAKY.
