Revert "[deoptimizer] Change deopt entries into builtins"

Browse Source 
This reverts commit 7f58ced72e.

Reason for revert: Segfaults on Atom_x64 https://ci.chromium.org/p/v8-internal/builders/ci/v8_linux64_atom_perf/5686?

Original change's description:
> [deoptimizer] Change deopt entries into builtins
>
> While the overall goal of this commit is to change deoptimization
> entries into builtins, there are multiple related things happening:
>
> - Deoptimization entries, formerly stubs (i.e. Code objects generated
>   at runtime, guaranteed to be immovable), have been converted into
>   builtins. The major restriction is that we now need to preserve the
>   kRootRegister, which was formerly used on most architectures to pass
>   the deoptimization id. The solution differs based on platform.
> - Renamed DEOPT_ENTRIES_OR_FOR_TESTING code kind to FOR_TESTING.
> - Removed heap/ support for immovable Code generation.
> - Removed the DeserializerData class (no longer needed).
> - arm64: to preserve 4-byte deopt exits, introduced a new optimization
>   in which the final jump to the deoptimization entry is generated
>   once per Code object, and deopt exits can continue to emit a
>   near-call.
> - arm,ia32,x64: change to fixed-size deopt exits. This reduces exit
>   sizes by 4/8, 5, and 5 bytes, respectively.
>
> On arm the deopt exit size is reduced from 12 (or 16) bytes to 8 bytes
> by using the same strategy as on arm64 (recalc deopt id from return
> address). Before:
>
>  e300a002       movw r10, <id>
>  e59fc024       ldr ip, [pc, <entry offset>]
>  e12fff3c       blx ip
>
> After:
>
>  e59acb35       ldr ip, [r10, <entry offset>]
>  e12fff3c       blx ip
>
> On arm64 the deopt exit size remains 4 bytes (or 8 bytes in same cases
> with CFI). Additionally, up to 4 builtin jumps are emitted per Code
> object (max 32 bytes added overhead per Code object). Before:
>
>  9401cdae       bl <entry offset>
>
> After:
>
>  # eager deoptimization entry jump.
>  f95b1f50       ldr x16, [x26, <eager entry offset>]
>  d61f0200       br x16
>  # lazy deoptimization entry jump.
>  f95b2b50       ldr x16, [x26, <lazy entry offset>]
