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.

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.

r11951 changed the existing check for the __SOFTFP__ define in ARM platforms
to a check for __SOFTP. Most other programs look for __SOFTFP__ [1], so
look for both to increase the chances of not erroring out when using GCC 4.5.

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.

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.
