Support for precise stepping in functions compiled before debugging was started (step 1)
...
This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

Avoid size increase of snapshot.
...
The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).
We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.
Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

Fix issue with prototype of WeakMap constructor.
...
The WeakMap constructor didn't have a unique prototype, so it shared one with
Object. All WeakMap functions (including "get" and "set") were installed on
that prototype.

Simplify handling of exits from with and catch.
...
Remove the try/finally used for with and catch. Instead of using
try/finally to handle break and continue from with or catch,
statically track nesting dept and clean up when compiling break or
continue.
And instead of using try/finally to handle throw to handler in a frame
whose pc is inside a with or catch, store the context that the handler
should run in in the handler itself.

Add roundsd instruction to ia32 and use it in optimized Math.floor.
...
It is available platforms that have SSE 4.1 and allows us to handle
negative numbers without deoptimization. Before we would deoptimize
on negative inputs to Math.floor. x64 already uses this instruction.
* Change Math.floor unit test to make sure every test case gets
optimized by changing the source code for each test case.
* Fix HIR debug printing for some instructions.
