LibJIT+LibJS: Move JIT::Assembler into a new LibJIT library
...
This will allow other parts of the system to generate machine code
at runtime. :^)

LibJS: Remove all interactions between Assembler and BasicBlock
...
With this change, Assembler is now free from LibJS concepts and could
move out to its own apartment. :^)

LibJS/JIT: Let Compiler keep per-BasicBlock state internally
...
Compiler now has a BasicBlockData struct for each BasicBlock. The struct
contains all the stuff that we previously stored with the
Bytecode::BasicBlock.

LibJS/JIT: Add fast path for LessThan Int32 < Int32
...
This uses a new branch_if_both_int32() helper.
It's interesting to note that we can compare encoded Int32 values
without stripping the INT32_TAG, since it doesn't affect signedness
of values.

LibJS/JIT: Add fast path for Increment with Int32 value
...
This uses a new branch_if_int32() mechanism that takes a code generating
lambda whose code will run if the input register is an Int32 JS::Value.

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: 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.
