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.

Runtime_DebugEvaluate creates an empty context which is not correctly handled in FullCodeGenerator::ContextSlotOperandCheckExtensions because the corresponding scope indicates that it has no context.

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.

We don't need to store the full representation for each value. Instead
a bit to indicate tagged/untagged is enough.

Reading the virtual register from a LOperand is only needed used for
unallocated LOperands (LUnallocated). There is no need for having a

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!
