LibJS/JIT: Add Assembler::jump(Operand) and verify_not_reached()
...
Yet another jump() overload, and also a way to crash if we end up
somewhere we shouldn't be while in jitted code.

LibJS/JIT: Propagate exceptions in the simplest case :^)
...
We now establish a stack of "unwind contexts" similar to what the
bytecode interpreter does, but here, it's a stack of structs with
addresses to the catch and finally blocks.
Unwind contexts also have a "valid" flag, and the root unwind context
(always present, pushed on JIT code entry) has valid=false, which we
interpret in check_exception() as "return and let our caller deal with
the exception".
Anything in Compiler that may generate an exception should now also
call check_exception() ASAP to emit the code for handling this.

LibJS/JIT: Do "enter & leave" sequence in x86_64 machine code
...
This ensures that the stack pointer is restored before we return from
the jitted code.

LibJS/JIT: Add Assembler::jump_if_equal()
...
And also factor out cmp() so we don't have to repeat it.
