Encapsulates all relevant GC thread-local-state into a separate structure. Motivation is that MMTk will have its own version of GC thread-local-state, so doesn't need all of the Julia GC TLS. In the future, folks who would be using MMTk would be setting a pre-processor flag which would lead to either the stock Julia GC TLS or MMTk's GC TLS to be included in `julia_threads.h`. I.e., we would have something like: ```C jl_gc_mmtk_tls_states mmtk_gc_tls; jl_gc_tls_states gc_tls; ```
Simplifies the layout of the doubly linked list of big objects to make it a bit more canonical: let's just store a pointer to the previous element, instead of storing a "pointer to the next element of the previous element". This should make the implementation a bit easier to understand without incurring any memory overhead. I ran the serial and multithreaded benchmarks from GCBenchmarks and this seems fairly close to performance neutral on my machine. We also ran our internal benchmarks on it at RAI and it looks fine from a correctness and performance point of view. --------- Co-authored-by: Kiran Pamnany <[email protected]>
They should have been deleted in JuliaLang#54936, but were not.
Third-party GCs (e.g. MMTk) will probably have their own function to spawn GC threads.

PR Description
Should be NFCs or code simplifications.
JuliaLang#54936 is the only one which does more significant changes, but we already assessed its performance in the open-source benchmarks and internally as well.
