op_is_foo should be optimized
https://bugs.webkit.org/show_bug.cgi?id=83666
Reviewed by Gavin Barraclough.
This implements inlining of op_is_undefined, op_is_string, op_is_number,
and op_is_boolean in LLInt and the baseline JIT. op_is_object and
op_is_function are not inlined because they are quite a bit more complex.
This also implements all of the op_is_foo opcodes in the DFG, but it does
not do any type profiling based optimizations, yet.
