4e18d50834 Add constant splitting for user controlled constants in the full compiler 
This is IA32 only for now.

Added a random value to each assembler instance (JIT cookie) to be used for constant splitting. Added safe versions of setting a register with an immediate value and for pushing an immediate value. Used these functions where user controlled immediate values could be emitted in the code stream. I also used it for immediates which are an argument number even though the number of formal arguments is currently limited to 16k.

I found no compares directly with user controlled constants.

I am not sure whether the test is that useful, but it might catch some changes missing constant splitting.

c10267f1fa Refactor HCheckInstanceType to allow mask/tag tests. 
This allows us to get rid of totally fake LAST_STRING_TYPE and makes
it possible to test for symbols.

I considered splitting HCheckInstanceType into two instructions, but
it seems nice to be able to hide the instance type implementation
details from the hydrogen level.

If the result of an fast elements load is converted to an untagged

anywhere else except for HChange instructions converting it to
an untagged representation since those will deoptimize for the hole
value anyway.

5b2e2636b7 Faster string equals in generated code. 
In my previous change I mixed up "compare" and "equals". This made us
miss the fast length check before comparing strings for equality.

Now we have a separate helper for "equals". It shares some of the
inner loop details with "compare". I'll see if this can be cleaned up
without making it unreadable.

4d1b2b1d38 Change the Hydrogen representation of uses. 
Rather than representing a use as a pointer to an HValue and then searching
for the specific (ambiguous) operand, we now represent a use as a pair of an
HValue and the input operand index.  Additionally, use a linked list instead
of a growable array list since we never use random access.

This allows us to remove a bunch of similarly named and subtly different
functions from the HValue API.  The cost in extra zone allocation per use is
partially offset by reusing use list nodes when replacing a use of one value
with another.
