07:35 PM Ruby Revision 4978bfb2 (git): ZJIT: `fmt::Debug` for VALUE in hex. Shorthand for rb_obj_info()

The default `{:?}` still always prints the pointer address and never
dereferences it, but now in hex.
The "alternate" flag lets you do `println!("{my_ruby_object:#?}")` and
get a rich printout like `VALUE(0x000000010232fd00 T_CLASS/Obje... alanwu (Alan Wu)

07:32 PM Ruby Revision 5ffaaf04 (git): ZJIT: Assert no side exits in assert_compiles()

Most of the time, we want to assert that we compile and the compiled
code runs without exiting. A small number of tests trigger side exits,
and those are changed to use assert_compiles_allowing_exits().
```console
$ rg -F 'assert_compil... alanwu (Alan Wu)

11:26 PM Ruby Revision 0c1ce03b (git): ZJIT: Make `hir::types::Class` not final and have it include metaclasses

Every class boots with a metaclass, and all metaclasses are subclasses
of Class, so `types::Class` has no business in `ExactBitsAndClass`.
In fact, we should never see an object whose RBasic::class is exactly
rb_cClass because classes ge... alanwu (Alan Wu)

12:17 AM Ruby Revision d2653493 (git): ZJIT: Guard `T_*` in addition to shape in polymorphic getivar

This is a8f3c34556 ("ZJIT: Add missing guard on ivar access on
T_{DATA,CLASS,MODULE}") but for the polymorphic implementation in HIR
build. alanwu (Alan Wu)

12:17 AM Ruby Revision 35346add (git): ZJIT: Print CUInt64 in hex when sign bit is set

It's likely some sort of mask or flags. Hexadecimal is more compact. alanwu (Alan Wu)

12:17 AM Ruby Revision 158c1fdb (git): ZJIT: Print the Cptr, not a pointer to the pointer

Previously, we had none-sensical lines such as:
```
v15:CPtr[CPtr(0x1008)] = Const CPtr(0x1010)
```
Which was a contradiction as the pointer in the type specialization
should match the pointer on the right hand side. alanwu (Alan Wu)

12:17 AM Ruby Revision fa8c9194 (git): ZJIT: Profiling: Separate bits for T_CLASS and T_MODULE

So I don't need to use is_subclass_of(). We already have two branches
for the two types during profiling anyways. alanwu (Alan Wu)
