MIPS: Fix lazy deoptimization at HInvokeFunction and enable target-recording call-function stub.

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.
