d38bbe354b 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.

411d21b2b1 Add start and end profiling time to v8::CpuProfile 
I'm going to change CPU profiler API and deprecate GetSelfTime, GetTotalTime and GetTotalSamplesCount on CpuProfileNode as all of those values are derived from self samples count and sampling rate. The sampling rate in turn is calculate based on the profiling duration so having start/end time and total sample count is enough for calculating smpling rate.

This fixes a deopt loop in the Epic Citadel demo and removes some code. Apart from that, this change is performance-neutral.

When we do something similar for BIT_NOT, the whole UnaryOp stuff can go away.

d2c443b774 Extract hardcoded error strings into a single place and replace them with enum. 
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.

Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:

It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.

From the other hand the developers have to add new strings into that enum.

a4c072ed47 Fix a crash when generating forward jumps to labels at very high assembly offsets 
The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.

Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

96fc677d25 Pipe a script's CORS status through V8 during compilation. 
In order to properly sanitize exception data during a 'window.onerror'
handler, we need to know whether a script was served with proper CORS
headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

6ba502fa4d 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.

(https://code.google.com/p/v8/issues/detail?id=2795)

The reason is when allocating and building arrays in hydrogen we need to ensure
we do any int32-to-smi conversions BEFORE the allocation. These conversions can
at least theoretically deoptimize. If this happens before all the fields of the
newly allocated object are filled in, we will have a corrupted heap.

372763897d Lazy call to custom stack trace formatting using Error.prepareStackTrace. 
This enables custom stack trace formatting for stack overflow.
A consequence is that stack trace formatting is now easily observable,
but we already established that the default stack trace formatting can
be observed anyways. It is only triggered by the .stack getter, and
it has to be explicitly called, (e.g. not implicitly after GC).
