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.

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.

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

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.

* This makes sure that DoModI calculates correct result even when
the left register is the same as the result register.
* Microoptmization: it generates smaller code when left and result
are different registers.

Test expectations can now include outcome: FLAKY.
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.
The slash correction for windows is now pulled into the test name method. Currently the progress output on windows contains a mixture of / and \.

If an developer attempts to "subclass" Error by running
`MyError.prototype = new Error();`, then the internal v8::Message object
that's produced and handed off to `window.onerror` handlers is poorly
stringified as "[object Object]".
This patch adjusts the stringification process for these objects to
include not only native Error objects, but also objects that have Error
in their prototype chain, and haven't overwritten Error.toString with
some custom variant.

The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this).
Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy.
It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy.
Both issues are now fixed and properly tested.

The start and end time are now measured in microseconds and the type is int64_t.
This way it seems more natural as we are going to support submilisecond sampling
rate soon. Also it fixes cctest/test-cpu-profiler/ProfileStartEndTime test
failure caused by comparison between long double and double.
