* Port setivar to the new backend IR
* Add a few more setivar test cases
* Prefer const_ptr

* Fix asm.load(VALUE)
- `<VALUE as impl Into<Opnd>>` didn't track that the value is a value
- `Iterator::map` doesn't evaluate the closure you give it until you
call `collect`. Use a for loop instead so we put the gc offsets
into the compiled block properly.
* x64: Mov(mem, VALUE) should load the value first
Tripped in codegen for putobject now that we are actually feeding
`Opnd::Value` into the backend.
* x64 split: Canonicallize VALUE loads
* Update yjit/src/backend/x86_64/mod.rs
* Port gen_send_cfunc to the new backend
* Remove an obsoleted test
* Add more cfunc tests
* Use csel_e instead and more into()

* Add a missing lea for build_kwargs
* Split cfunc test cases

forward_pass adjusts the indexes of our opnds to reflect the new
instructions as they are generated in the forward pass. However, we were
using the old live_ranges array, for which the new indexes are
incorrect.
This caused us to previously generate an IR which contained unnecessary
trivial load instructions (ex. mov rax, rax), because it was looking at
the wrong lifespans. Presumably this could also cause bugs because the
lifespan of the incorrectly considered operand idx could be short.
We've added an assert which would have failed on the previous trivial
case (but not necessarily all cases).

* Convert getinstancevariable to new backend IR
* Support mem-based mem
* Use more into()
* Add tests for getivar
* Just load obj_opnd to a register
* Apply another into()
* Flip the nil-out condition
* Fix duplicated counts of side_exit
* Move allocation into Assembler::pos_marker
We wanted to do this to begin with but didn't because we were confused
about the lifetime parameter. It's actually talking about the lifetime
of the references that the closure captures. Since all of our usages
capture no references (they use `move`), it's fine to put a `+ 'static`
here.
* Use optional token syntax for calling convention macro
* Explicitly request C ABI on ARM
It looks like the Rust calling convention for functions are the same as
the C ABI for now and it's unlikely to change, but it's easy for us to
be explicit here. I also tried saying `extern "aapcs"` but that
unfortunately doesn't work.
* A64: Fix off by one in offset encoding for BL
It's relative to the address of the instruction not the end of it.
* A64: Fix off by one when encoding B
It's relative to the start of the instruction not the end.
* A64: Add some tests for boundary offsets
It allows for reserving a specific register and prevents the register
allocator from clobbering it. Without this
`./miniruby --yjit-stats --yjit-callthreshold=1 -e0` was crashing because
the counter incrementing code was clobbering RAX incorrectly.
* Better splitting for Op::Add, Op::Sub, and Op::Cmp
* Split stores if the displacement is too large
* Use a shifted immediate argument
* Split all places where shifted immediates are used
* Add more tests to the cirrus workflow
