fschneider@chromium.org b93a0f5d9a Second attempt: Improve our type feedback by recogizining never-executed IC calls for binary operations. 
This is an improved version of my earlier change r5970. It avoids degrading the
non-optimized code.

Initially we emit a conditional branch that is either always- or never-taken
after a smi-check (depending on whether we test for smi for for non-smi)
Since test-eax always sets the carry-flag to 0 we use jump-if-carry and
jump-if-not-carry.

The first invocation of the stub patches a jc with a jz and
jnc with a jnz-instruction so that the code looks exactly as it was
without patching. The only difference is the test- or nop-instruction
after the IC-call.
