5f29f9bd8e Don't use environment values at certain deoptimize-instructions.
If a HDeoptimize does not cut away parts of the control-flow-graph
we don't need to insert uses to correctly elimiate dead phis since
the full function is visible to the optimizing compiler.

This is a small improvement of the change r7221 which fixed a problem
when deoptimizing on never executed case-clauses.

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.

4912c0371b A few "extract method" refactorings, trying to get individual method definitions
onto a sinlge 30" screen. A lot of times, the AST visitor stops a bit too early,
so we have to do the rest of the dispatch by hand. This is caused by the fact
that the kind of the AST nodes are a bit too coarse for some traversals (e.g. a
single node type for all binary ops), perhaps one could try to refine this a
little bit more.
