In some circumstances, try/finally block can actually catch the exception:

function f() {
  try {
    throw 42;
  } finally {
    return 0;
  }
}

Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.

When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.

Plus various minor refactorings.

In revision 6795 I introduced an assertion in the deoptimizer that was
wrong. We check that curr_address - prev_address > patch_size(), but
prev_address is actually the address right after the last patched
call, so we just need to be larger than or equal to prev_address.

Make sure we always have room for patching the reloc info during lazy deoptimization (fixes issue 1156).

Before we could have calls to builtins that would not be in the
relocation info since this used a register as target. Whenever we have
this case (from lithium codegen) we now emit a comment in the reloc
info.

Rather than passing in a pair of unequal-length lists, pass the default
subgraph separately.  Construct the typecase from the top down rather than
the bottom up, so it doesn't need an intermediate zone list.

Also, change a basic block's 'last' instruction field to really be its last
instruction by correctly updating it when inserting and removing
instructions.
