* Remove an unused variable
* Write up a document about testing
* Explain zjit-test-all first
* Clarify what's zjit-test-all
* Add RPO
* Add basic flow typing
* Add more tests, check for type bit equality
* Run to fixpoint
* Only use/flow types if insn has an output
* WIP
* WIP 2: merge pred args
* It compiles again
* Infer more Const instructions
* Boot VM
* Test displaying types
* .
* Use type_of more
* Extract Param inference into its own function for readability

This requires computing "uses", or at least which blocks to revisit if
their params change.
* Just use a set
* Revert "Just use a set"
This reverts commit 54d88be00cbf78ce7e928c66d955c968187a5ec9.
* Revert "Use worklist based type inference"
This reverts commit e99b24629723c8848fefd5a75caa23e84c2f552e.

This is a left-over from https://github.com/Shopify/zjit/pull/12.
It was supposed to be removed from both workflows in the PR, but this
was somehow uncommitted.
The 2024 edition pointed out that setting env vars in multiple threaded
programs is unsafe, due to it being thread unsafe in glibc. Sure don't
want to crash while already crashing! Always grab a backtrace with
force_backtrace().
