[turbofan] Introduce ToBooleanHints on ToBoolean operators.

Extract ToBoolean hints from the fullcodegen code object and put them
into the ToBoolean nodes created by the AstGraphBuilder.  We currently
do not yet consume this feedback, that will be done in a followup CL.

Hey Michi,

Here's the CL to introduce ToBoolean operator hints. Manually verified that we
take the correct test_id (can't wait to drop the fullcodegen gymnastics tho).
Please take a look.

Thanks,
Benedikt
