25c71e6f39 X64: Fix bug in minus-zero check after int32 multiplication. 
In optimized x64 code, the check for minus zero after multiplication
used the wrong size bit-or instruction (64-bit instead of 32-bit).

b34e202b20 Removed IsTransitionType predicate. 
With the upcoming changes to CALLBACKS properties, a predicate on the transition
type alone doesn't make sense anymore: For CALLBACKS one has to look into the
property's value to decide, and there is even the possibility of having a an
accessor function *and* a transition in the same property.

I am not completely happy with some parts of this CL, because they contain
redundant code, but given the various representations we currently have for
property type/value pairs, I can see no easy way around that. Perhaps one can
improve this a bit in a different CL, the current diversity really, really hurts
productivity...

As a bonus, this CL includes a few minor things:

 * CaseClause::RecordTypeFeedback has been cleaned up and it handles the
   NULL_DESCRIPTOR case correctly now. Under some (very unlikely) circumstances,
   we previously missed some opportunities for monomorphic calls. In general, it
   is rather unfortunate that NULL_DESCRIPTOR "shines through", it is just a
   hack for the inability to remove a descriptor entry during GC, something
   callers shouldn't have to be aware of.

 * DescriptorArray::CopyInsert has been cleaned up a bit, preparing it for later
   CALLBACKS-related changes.

 * LookupResult::Print is now more informative for CONSTANT_TRANSITION.

0ec7773680 Allow bailing out of the register allocator when running out of virtual registers. 
1. Instead of checking upfront and estimating a limit for the number, we
now are able to stop register allocation and bailout when we don't
have enough virtual registers.

2. GCed some out-dated flags from flag-definition.h

3. Simplified the interface from the Lithium builder to the
register allocator in lithium-*.cc: For uses and definitions, we
just record the virtual register number given by the Hydrogen value id.
For temporaries, we request a new virtual register from the allocator.
For fixed temps, we don't need to do anything.

4. Increased number of deoptimization entries to 16K. Eventually we
probably want to make this array grow dynamically.

82d1f51534 Give uses within a loop a greater weight when doing representation inference. 
Uses of a value are weighted by a factor of FLAG_loop_weight (default: 10) for
every loop they are in. This makes uses in inner loops "more important", which
should improve the result of the representation inference.

375be4ae25 Inline an inline function into the CHECK macro 
CheckHelper was only used within the macro itself. Furthermore, GCC
with -Winline was not always happy with the inline function. Simple
solution: Inline the inline function into the macro itself. Inlining
squared!

9ece818b56 MIPS: Implement target cache for constructor calls. 
Port r10531 (d61db240).

Original commit message:

This caches call targets of constructor calls by associating one element
caches with call sites. The type feedback oracle can use the recorded
valued to gather type information for monomorphic constructor call sites.
