33ddb37ba3 Removed confusing defensive programming in GenerateJumpTable. 
For a given address/type pair we should always find a deoptimization
bailout ID, otherwise something is wrong. This was already asserted on
ARM, but we now do this consistently on all platforms.

Removed some usesless naming creativity on the way.

27f3cc1b9c Require V8 to be explicitly initialized before an Isolate is created 
We also initialize the Isolate on creation.

This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.

Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.

first go to flag-definitions.h and set this to false.

134a89b11f Introduce TypeFeedbackVector, as FixedArray grew constrictive. 
The TypeFeedbackVector is poised to host significant functionality. While it
remains a FixedArray under the covers, we need a place to hold logic and
definitions unique to its function.

80d9d6df30 Thread the Lithium instruction down to DeoptimizeIf and friends. 
This is a purely mechanical refactoring and a first step towards being
able to report more helpful deoptimization reasons. With this
refactoring, we know at least the mnemonic of the instruction causing
the deopt, although this is not used yet. Future steps will be using
the mnemonic, passing additional explicit deopt reasons and removing
the fragile machinery of searching for code comments.
