Discern between NaNs that would be safe to tag and NaNs that need some purification before tagging
https://bugs.webkit.org/show_bug.cgi?id=131420

Reviewed by Oliver Hunt.
        
Rationalizes our handling of NaNs. We now have the notion of pureNaN(), or PNaN, which
replaces QNaN and represents a "safe" NaN for our tagging purposes. NaN purification now
goes through the purifyNaN() API.
        
SpeculatedType and its clients can now distinguish between a PureNaN and an ImpureNaN.
        
Prediction propagator is made slightly more cautious when dealing with NaNs. It doesn't
have to be too cautious since most prediction-based logic only cares about whether or not
a value could be an integer.
        
AI is made much more cautious when dealing with NaNs. We don't yet introduce ImpureNaN
anywhere in the compiler, but when we do, we ought to be able to trust AI to propagate it
soundly and precisely.

Crash in CodeBlock::setOptimizationThresholdBasedOnCompilationResult() when the debugger activates.
<https://webkit.org/b/131747>

Reviewed by Filip Pizlo.

When the debugger is about to activate (e.g. enter stepping mode), it first
waits for all DFG compilations to complete.  However, when the DFG completes,
if compilation is successful, it will install a new DFG codeBlock.  The
CodeBlock installation process is required to register codeBlocks with the
debugger.  Debugger::registerCodeBlock() will eventually call
CodeBlock::setSteppingMode() which may jettison the DFG codeBlock that we're
trying to install.  Thereafter, chaos ensues.

This jettison'ing only happens because the debugger currently set its
m_steppingMode flag before waiting for compilation to complete.  The fix is
simply to set that flag only after compilation is complete.

Web Replay: memoize fallback time values for document.lastModified

Source/WebCore:
If a document's Last-Modified header can't be found or used, then
document.lastModified is derived from the current system time or

It's better to handle this inside Document::lastModified rather than using
MemoizedDOMResult, because only the fallback case is nondeterministic.

-Sticky top and bottom like the UIProcess.
-Keep the same relative position of the unobscured rect's center.

Also fix a bug in the horizontal and vertical adjustments: the code was using the exposed rect
instead of the unobscured rect, which made the adjustments off by the size of the obscured insets.
