Fix the Mac build. "_toolset" needs to be tested inside target_conditions now.

And there is no need to have -llog any more.

Port r9977 (9aded78be4).
Note: This is the port of the reapplied patch, not the original.

Original commit message:

To support deoptimization of exception handlers, the handler address in the
stack is converted to a pair of code object and an index into a separate
table of code offsets.  The index part is invariant under deoptimization.
The index is packed into the handler state field so that handler size does
not change.

This generates code stubs for cloning of shallow object literal
boilerplates that have no elements and only fast properties. Improves
splay performance because object literals are created frequently.

Port r10006 (4b344a03).

Original commit message:

Changes the way we do lazy deoptimization:

1. For side-effect instructions, we insert the lazy-deopt call at
the following LLazyBailout instruction.

     CALL
     GAP
     LAZY-BAILOUT ==> lazy-deopt-call

2. For other instructions (StackCheck) we insert it right after the
instruction since the deopt targets an earlier deoptimization environment.

   STACK-CHECK
   GAP ==> lazy-deopt-call

The pc of the lazy-deopt call that will be patched in is recorded in the
deoptimization input data. Each Lithium instruction can have 0..n safepoints.
All safepoints get the deoptimization index of the associated LAZY-BAILOUT
instruction. On lazy deoptimization we use the return-pc to find the safepoint.
The safepoint tells us the deoptimization index, which in turn finds us the
PC where to insert the lazy-deopt-call.

Additional changes:
* RegExpLiteral marked it as having side-effects so that it
  gets an explicitlazy-bailout instruction (instead of
  treating it specially like stack-checks)
* Enable target recording CallFunctionStub to achieve
  more inlining on optimized code.

Changes:
-separated the two code-paths (constant power of 2 divisor similar to ARM and everything else)
-replaced a bailout condition with faster handling (negative modulo result)
-removed a possibly useless mov instruction from one path
-replaced the IsConstantOperand condition with the more meaningful HasPowerOf2Divisor (although in this specific case they're equivalent)
