096e1972cd Work-around to make webkit test suite work with optdebug==2. 
The test driver doesn't know at the moment if optdebug 1 or 2 has been used (the first is used on the bots, the second
locally in quickcheck). It can't know therefore if slow
asserts can be enabled or not. Trying to enable them leads
to a warning if they weren't compiled, which causes webkit
1:1 text comparison to fail.

c61abc1426 [turbofan] Materialize the correct kind of constant for bit 1. 
Bit 1 should be represented as Int32Constant 1 after simplified

This issue is exposed by CL https://codereview.chromium.org/807273003.

  The DeoptimizeIf(...) function will generate more Assembler code and the
  distance between the link point and the bind point is larger then near
  link distance (127) for labels.

7d478d9621 Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) 
Reason for revert:
Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/

I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

87e4bba31e Support multiple interrupt requests in v8 API. 
There might be a number of clients that would like to
setup an interrupt request on the Isolate.

The patch also deprecates ClearInterrupt API. As long as
the interrupt handler is called outside of locks there's no way
to guarantee that the handler will not be called after
ClearInterrupt was invoked as it might have already started execution.

50b7ca5593 Improved --trace-opt output a bit. 
This ensures that we always have a kind of "brace" around the actual compilation
with --trace-opt. Previously this was coupled to --trace-hydrogen for
Crankshaft, and there was no output at the start of the compilation for
TurboFan.

Removed redundant "[completed...]" output: Whenever the compilation was
successful, we have already printed "[optimizing...took...]".

Output total TurboFanning time with --trace-opt, too (basically as graph
building time, this is rather arbitrary).

f4fb702569 Make FlushICache NOP for Nvidia Denver CPU's. 
Denver supports a coherent cache mechanism. There is no need to clean
the D cache and invalidate I cache. MTS has to check the translation
anytime there is an I cache invalidate and this time can be saved by
making FlushICache a NOP.

The patch improves Octane by roughly 3-4% on Denver.
