bc609aff70 Merge RecordComment invocations into DeoptimizeIf calls. 
This way the deoptimization reasons are actually threaded through to
the jump table. Tiny cleanup of related MIPS/MIPS64 code on the way.

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.

Note that we still need to migrate from sometimes emitting those

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.

ac1b9b11dc Fixed deopt reasons in TaggedToI. 
Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.

On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.

Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

a4176d2052 Removing ic.h from code-stubs.h 
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

febf84a333 Added CallInterfaceDescriptors to all code stubs. A handful 
of code stubs are too complex to be described this way, and
they are encoded with the macro
DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

Along the way:
* allowed inheritance of CallInterfaceDescriptors.
* Defined static Register methods for some of the new
  CallInterfaceDescriptors. We could go a lot further here, but
  it doesn't have to be done immediately.
* Added Representation arrays to some CallInterfaceDescriptors,
  especially where future hydrogen versions of the stubs could
  benefit from this knowledge.

76e22ca629 Added vector-based loadic hydrogen stubs. Not yet callable. 
The next step is to integrate the use of vector[slot] into the IC
infrastructure so it can do the right thing for a vector-based ic.
Then these stubs can be installed. For now, they immediately bail out
to the miss handler.

295448a4ea Move register conventions out of the IC classes. 
A change to a convention shouldn't require recompilation of ic.h/.cc.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.
