Instance-type-related fixes and cleanup.
...
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.

MIPS: Patch to enhance the source code line information for profiler.
...
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.

Deprecate self and total time getters and total sample count getter on CpuProfileNode
...
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.

MIPS: First implementation of allocation elimination in Hydrogen.

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.

Improve internal stringifcation for custom Error objects.
...
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.

I found this working on
...
https://codereview.chromium.org/19541010/
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.

Return start/end profiling time in microseconds instead of milliseconds
...
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.

MIPS: Migrate instance of deprecated maps in HCheckMaps.
...
Port r16057 (b73ae514)
Original commit message:
Currently only direct map checks are supported. Otherwise only polymorphic cases with a generic fallback behave properly, regular polymorphic cases still need to be adapted.

Use first hit when dumping heap constants.
...
This makes sure that the first hit is used when dumping heap constants
and hence "TheHoleValue" is not overwritten with other roots that are
initialized to the hole as well.
