Change the default --jit-max-cache to 10000 
This is useful for large applications like Rails.

Evaluate multiple assignment left hand side before right hand side 
In regular assignment, Ruby evaluates the left hand side before
the right hand side.  For example:

```ruby
foo[0] = bar
```

Calls `foo`, then `bar`, then `[]=` on the result of `foo`.

Previously, multiple assignment didn't work this way.  If you did:

```ruby
abc.def, foo[0] = bar, baz
```

Ruby would previously call `bar`, then `baz`, then `abc`, then
`def=` on the result of `abc`, then `foo`, then `[]=` on the
result of `foo`.

This change makes multiple assignment similar to single assignment,
changing the evaluation order of the above multiple assignment code
to calling `abc`, then `foo`, then `bar`, then `baz`, then `def=` on
the result of `abc`, then `[]=` on the result of `foo`.

Implementing this is challenging with the stack-based virtual machine.
We need to keep track of all of the left hand side attribute setter
receivers and setter arguments, and then keep track of the stack level
while handling the assignment processing, so we can issue the
appropriate topn instructions to get the receiver.  Here's an example
of how the multiple assignment is executed, showing the stack and
instructions:

```
self                                      # putself
abc                                       # send
abc, self                                 # putself
abc, foo                                  # send
abc, foo, 0                               # putobject 0
abc, foo, 0, [bar, baz]                   # evaluate RHS
abc, foo, 0, [bar, baz], baz, bar         # expandarray
abc, foo, 0, [bar, baz], baz, bar, abc    # topn 5
abc, foo, 0, [bar, baz], baz, abc, bar    # swap
abc, foo, 0, [bar, baz], baz, def=        # send
abc, foo, 0, [bar, baz], baz              # pop
abc, foo, 0, [bar, baz], baz, foo         # topn 3
abc, foo, 0, [bar, baz], baz, foo, 0      # topn 3
abc, foo, 0, [bar, baz], baz, foo, 0, baz # topn 2
abc, foo, 0, [bar, baz], baz, []=         # send
abc, foo, 0, [bar, baz], baz              # pop
abc, foo, 0, [bar, baz]                   # pop
[bar, baz], foo, 0, [bar, baz]            # setn 3
[bar, baz], foo, 0                        # pop
[bar, baz], foo                           # pop
[bar, baz]                                # pop
```

As multiple assignment must deal with splats, post args, and any level
of nesting, it gets quite a bit more complex than this in non-trivial
cases. To handle this, struct masgn_state is added to keep
track of the overall state of the mass assignment, which stores a linked
list of struct masgn_attrasgn, one for each assigned attribute.

This adds a new optimization that replaces a topn 1/pop instruction
combination with a single swap instruction for multiple assignment
to non-aref attributes.

This new approach isn't compatible with one of the optimizations
previously used, in the case where the multiple assignment return value
was not needed, there was no lhs splat, and one of the left hand side
used an attribute setter.  This removes that optimization. Removing
the optimization allowed for removing the POP_ELEMENT and adjust_stack
functions.

This adds a benchmark to measure how much slower multiple
assignment is with the correct evaluation order.

This benchmark shows:

* 4-9% decrease for attribute sets
* 14-23% decrease for array member sets
* Basically same speed for local variable sets

Importantly, it shows no significant difference between the popped
(where return value of the multiple assignment is not needed) and
!popped (where return value of the multiple assignment is needed)
cases for attribute and array member sets.  This indicates the
previous optimization, which was dropped in the evaluation
order fix and only affected the popped case, is not important to
performance.

Jeremy Evans e09094546a Make Module#prepend affect ancestor chain even if argument already included in receiver 
Previously, if a class included a module and then prepended the
same module, the prepend had no effect.  This changes the behavior
so that the prepend has an effect unless the module is already
prepended the receiver.

While here, rename the origin_seen variable in include_modules_at,
since it is misleading. The variable tracks whether c has been seen,
not whether the origin of klass has been.

Rename RubyVM::MJIT to RubyVM::JIT 
because the name "MJIT" is an internal code name, it's inconsistent with
--jit while they are related to each other, and I want to discourage future
JIT implementation-specific (e.g. MJIT-specific) APIs by this rename.
