- Restructure the runtime function implementation.
- Rename osr_loop_nesting_level to osr_urgency and add helpers.

The motivation for the latter: I've always struggled with the
`osr_loop_nesting_level` term; it neither matches terminology of
what it's compared against (= the loop depth), nor implies what it's
used for (= osr is triggered when `loop depth < osr nesting level`).

In this CL it's renamed to `osr_urgency` to reflect that as urgency
rises, we consider more and more loops as OSR candidates.

Modernise the RegList interface to be a proper class, rather than a
typedef to an integer, and add proper methods onto it rather than ad-hoc
bit manipulation.

In particular, this makes RegList typesafe, adding a DoubleRegList for
DoubleRegisters.

The Arm64 CPURegList isn't updated to use (or extend) the new RegList
interface, because of its weird type-erasing semantics (it can store
Registers and VRegisters). Maybe in the future we'll want to get rid of
CPURegList entirely and use RegList/DoubleRegList directly.

This is in preparation for baseline code flushing. After a deopt we
choose to execute baseline or bytecode based on whether
SharedFunctionInfo has any baseline code. With baseline code flushing,
it is possible that baseline code is flushed after this point and before
we start executing the unoptimized code (for ex: materializing objects).
To handle such situations this CL updates the BaselineEnterAt* builtins
to check for baseline code and restart either at baseline / bytecode.

Various behaviour preserving changes that make it easier to switch on
callee-saved registers without having to land refactoring code at the
same time.

- Use MaybeStoreRegisters / MaybeRestoreRegisters
- Use CallRecordWriteStubSaveRegisters everywhere for now. Eventually
  this will be replaced by CallRecordWriteStub in places with fixed
  registers.
- Use WriteBarrierDescriptor::ComputeSavedRegisters, which for now
  returns the same as allocatable_registers
