Mapping the code offsets between code with and without debug break slots
requires information about the size of the veneer pools and constant pools.

The ool constant pool will require a pointer to the code's constant pool when
updating or reading target addresses using set_target_address_at()
and target_address_at().

This patch also modify the crankshaft allocatable double registers because
we need this register to be callee saved to be efficient.

This replaces Tmp0() and Tmp1() with a more flexible scratch register
pool. A scope-based utility can temporarily acquire registers from this
pool as needed.

We no longer have to worry about whether to use Tmp0(), Tmp1() or
something else; the scope can just get the next available scratch
register.

The previous heuristic would break as a significant amount of code could be
generated without checking for veneer emission.
The veneer emission is now done in the Assembler, in a very similar way to
constant pool emission.

Code generation would fail when assembling a branch to a label that is bound
outside the immediate range of the instruction. A64 is sensitive to this, as the
various branching instructions have different ranges, going down to +-32KB for
TBZ/TBNZ.  The MacroAssembler is augmented to handle branches to targets that
may exceed the immediate range of instructions.

When branching backward to a label exceeding the instruction range, the
MacroAssembler can simply tweak the generated code to use an unconditional
branch with a longer range. For example instead of
    B(cond, &label);
the MacroAssembler can generate:
    b(InvertCondition(cond), &done);
    b(&label);
    bind(&done);

Since the target is not known when the branch is emitted, forward branches uses
a different mechanism. The MacroAssembler keeps track of forward branches to
unbound labels. When the code generation approaches the end of the range of a
branch, a veneer is generated for the branch.

Added support for truncating DoubleToIStub and reorganize the macro-assembler
dToI operations to do the fast-path inline and the slow path by calling the
stub.

This a port essentially a port of https://codereview.chromium.org/23129003/.
